Three full PC games have verified Steam offers this weekend: Sid Meier’s Civilization VII and First Class Trouble are paid games with temporary free access, while the released Chapter 1 of Legends of Starkadia is free to claim now and remains in your library after its planned switch to a $1.99 paid game.[1][4][10]
Verified: September 5, 2026 at 10:08 a.m. Eastern (14:08 UTC) · U.S. Steam storefront · prices in U.S. dollars. Store availability and pricing can differ by region.
The quick answer: two clocks expire, one claim lasts
First Class Trouble: free access ends Monday, September 7 at 1 p.m. EDT (10 a.m. PT). Steam’s live page shows “Play for free until Sep 7 @ 10:00am,” and its StoreBrowse interval ends at the matching Unix timestamp.[4]
Civilization VII: its longer Free Play Week ends Thursday, September 10 at 1 p.m. EDT (10 a.m. PT). 2K’s Steam announcement gives the same window and says progress and achievements carry over if you later buy the game on Steam.[2]
Legends of Starkadia: claim the released base game before its planned September 14 conversion to $1.99. Doom Turtle supplies no cutoff hour, so claim before that date rather than assuming the whole day is available. Existing owners keep it forever for free.[10]
Ownership warning: Civilization VII and First Class Trouble expire; installing them does not create permanent ownership. Legends of Starkadia is the opposite: claim it now and the developer says the license remains in your library.[2][5][10]
Which one should you download or claim?
Civilization VII
Choose this if you want turn-based empire building, campaigns that move through Antiquity, Exploration and Modern Ages, or cross-platform multiplayer. The free window is long enough to learn the systems and finish a focused single-Age session, but a sprawling campaign can easily outlast a weekend.
First Class Trouble
Choose this if you have friends available for voice-chat deception. Residents try to shut down CAIN while hidden Personoids sabotage the group. Standard matches use six players; custom games support four to twelve.[6]
Legends of Starkadia
Claim this even if you cannot play today. It is a short, released turn-based RPG chapter—not a demo—and Doom Turtle says existing owners keep it after the September 14 paid transition.[10][11]
Free Play Week · through Sept. 10
Sid Meier’s Civilization VII
Free temporarily · normally $69.99 · currently $34.99 (50% off) through September 17 at 1 p.m. EDT.[1]
Identity, genre and platforms were verified through Steam’s official app record.[3]
What it is
Civilization VII asks you to lead an empire across three distinct Ages. Leaders are selected separately from civilizations, settlements can grow into specialized towns or cities, and campaigns can pursue scientific, cultural, military or economic milestones. It supports solo play and online multiplayer; Steam lists cross-platform multiplayer, and 2K says online campaigns can be multi-Age or limited to one Age.[3]
How to use the free week well
Start with the tutorial or one compact single-player game rather than your largest possible map. The long window makes this the better solo choice: you can learn settlement placement, technology and civic choices, diplomacy, commanders and the Age-transition system without trying to consume an entire strategy game in one night. If multiplayer is the goal, organize the group before installing; online features require internet access and a 2K account linked to the platform account, while offline play does not require that account.[3]
Good fit
Players who like deliberate turn-based planning, historical remixing, several victory paths, solo campaigns and online strategy. Progress and Steam achievements are explicitly eligible to carry into a purchased copy on the same platform.[2]
Know before installing
The Steam listing discloses Denuvo Anti-tamper with a five-activations-per-24-hours machine limit. Windows requires DirectX 12. The listed 20–25 GB storage figure is a requirement, not a guaranteed download size, and updates can add transfer or disk overhead.[3]

Free weekend · through Sept. 7
First Class Trouble
Free temporarily · normally $14.99 · currently $4.49 (70% off) through September 17 at 1 p.m. EDT.[4]
Identity, genre and platform were verified through Steam’s official app record.[6]
What it is
Aboard the ISS Alithea, human Residents try to shut down the ship’s Central Artificial Intelligence Network, CAIN. Hidden Personoids look human but work against the group, using lies, sabotage and environmental hazards. The store describes proximity voice chat, text chat, an emote wheel, themed levels, six-player standard games and four-to-twelve-player custom games.[6]
Why this is the weekend-first download
The shorter access clock makes it the priority. It also depends on active players: install with friends, confirm everyone has a working microphone, and allow time to learn the social rules. This is not a linear campaign to “finish”; its value comes from repeated rounds and reading—or misleading—the people in your lobby.
Good fit
Groups who like bluffing, proximity chat, improvised betrayals and short rounds. A familiar friend group can lower the friction of finding a lobby and makes voice recognition part of the fun.
Know before installing
Steam lists Windows 10 64-bit, broadband internet and a microphone at minimum; recommended equipment adds headphones. This is multiplayer-only on Steam, and the store lists neither macOS nor Linux support.[6]
Why the announcement and store show different calendar wording
The publisher announcement describes a “September 3rd–September 6th” free weekend, but Steam’s precise live purchase block says access ends September 7 at 10 a.m. PT, and the StoreBrowse timestamp matches that Monday endpoint. For action, use the live Steam deadline: Monday, September 7 at 1 p.m. EDT.[4][5]

Free to claim and keep · paid transition Sept. 14
Legends of Starkadia
Free now · planned price $1.99 beginning September 14 · existing owners keep it forever.[10]
Identity, release type and platform were verified through Steam’s official app record.[11]
What it is—and what it is not
Legends of Starkadia is a released base-game app, separate from its demo. It combines turn-based combat with quick-time events, side missions and a roster of 12 unlockable characters. The Steam page says the current adventure contains one planet and should take about two hours; its planned 11-planet story has been written but not developed.[11]
Why you should claim it now
This offer does not use Steam’s usual temporary 100%-discount purchase widget. The game is currently free-to-play, and Doom Turtle has announced a business-model change: on September 14 it plans to charge $1.99, while accounts that already own the game keep it forever for free. The announcement provides a date but no clock or timezone, so the conservative move is to add it to your library before September 14.[10]
Good fit
Players who enjoy colorful single-player RPGs, turn-based tactics, quick-time inputs and compact adventures. Because ownership persists, this is the one offer you can claim now and play after the promotional change.[10]

Steam lists Windows 7 as the game minimum, but separately warns that the Steam client itself supports only Windows 10 and later; current users should treat Windows 10 as the practical floor.[11]

How to start or claim the games
- Sign in to the Steam desktop client with your own account.
- For Civilization VII or First Class Trouble, open the direct store link and confirm it still shows “Play Game” plus the expected free-access deadline.[1][4]
- For Legends of Starkadia, add the released base game—not app 4680910’s separate demo—to your library before September 14. Steam currently labels the base app “Free To Play,” and Doom Turtle says existing owners retain it after the transition.[9][10]
- Choose an install location with more free space than the listed requirement. For Civilization VII multiplayer, prepare a 2K account; for First Class Trouble, test the microphone and headphones before gathering the group.[3][6]
- If you buy either temporary-play game, verify the edition and final checkout price. Its free-play endpoint and purchase-sale endpoint are separate.
Free play and free to keep are different
Free play/free weekend means temporary access to a paid game. Free to keep means a claim creates continuing ownership. Civilization VII and First Class Trouble expose Steam free-weekend blocks and expire at their listed endpoints; neither page exposes a zero-price permanent-license form.[1][4]
Legends of Starkadia qualifies by a different path: it is a released free base game—not a demo or conventional giveaway widget—and Doom Turtle explicitly promises that owners before the September 14 paid transition keep it forever.[10][11]
Frequently asked questions
Can I keep playing after the deadline if the game remains installed?
No. The temporary license expires even if the files remain on the computer. Civilization VII’s official notice explicitly says the game must be purchased on the same platform to continue after the event.[2]
Will Civilization VII progress carry into a purchase?
2K says progress and achievements carry over to purchased games on the same platform.[2] Cloud synchronization can still depend on the platform and account state, so confirm Steam Cloud status before changing PCs.
Do I need a subscription?
None of the three verified Steam offers lists a paid subscription as a condition. You need a Steam account and client. Civilization VII’s online interactions require internet and a 2K account; its Steam notice says offline play does not require the 2K account.[3][6][11]
Which game is better for solo play?
Civilization VII is the deepest solo option; Legends of Starkadia is the shorter one. Steam categorizes both for single-player, while First Class Trouble is multiplayer-only.[3][6][11]
What should I do first?
Add Legends of Starkadia to your library so the developer’s keep-forever promise applies, then download First Class Trouble because its temporary access ends first. If bandwidth is limited, queue Civilization VII last and recheck each live page before acting.[1][4][10]
Can The IT Guys help if Steam will not install or launch?
Yes. We can help Treasure Coast PC players diagnose low disk space, Windows and graphics-driver problems, launcher failures, microphone issues and game crashes. We cannot extend a promotion, change Steam licensing, bypass DRM or guarantee a particular game will run on unsupported hardware.
How we verified this list
We froze the cutoff, U.S. region and promotion definitions first; used current search and third-party trackers only to discover candidates; then required direct official Steam evidence for every retained game. The two temporary offers have live free-weekend blocks, official announcements and StoreBrowse intervals. Legends of Starkadia has a live released base-game page plus Doom Turtle’s explicit keep-forever transition notice. Steam’s featured endpoints were incomplete, and a high-volume specials scan hit HTTP 429, so this is a bounded snapshot—not a guarantee that no newly launched, regional or account-targeted offer exists. Multiple independent discovery routes converged on these three offers, and all three were rechecked directly.[13][14]
