You know the Next Fest feeling. You open Steam, see a wall of demo tiles, download eleven of them "for later", and two weeks later they're still sat on your SSD, unplayed, quietly eating your storage. I'd like to stop that happening to you.
Steam Next Fest is back three times in 2027. Valve's confirmed calendar has a February edition and 14–21 June 2027, with another one expected later in the year. I'm not going to list every demo. The point here is working out what each demo can actually tell you before you spend any money.
Valve describes Next Fest as a multi-day event with playable demos, developer livestreams and upcoming games. Dates and eligibility can change, so keep an eye on the Steam events calendar.
What actually is Next Fest?
It's a discovery event for Steam games that haven't come out yet. Developers can put up demos, stream themselves playing and answer questions. Some demos stay up afterwards, but taking part in the event doesn't mean a demo sticks around for good.
SteamSteamValve's PC game storefront and library, including direct game purchases, demos and Steam hardware pages.Buying guide · View store →'s earlier official trailer gives you the idea: quick-fire intros to loads of demos, each leading to a store page where you download and try it.
That's an old trailer to show how the event works. It's not a list of who's taking part in 2027.
When are the 2027 dates?
Valve's published schedule has Next Fest in February and from 14–21 June 2027. Check Steam itself before you book a week off around it (no judgement). Store events usually start and finish at a fixed global time, so the UK date can look a day off around midnight.
The June edition finishes ten days before the Steam Summer Sale starts on 24 June. Don't mix them up: demos are for games that aren't out yet, and the sale is for games that are. A game you loved in a demo won't necessarily be on sale straight away.
How do I pick which demos to play?
Ignore the popularity grid. A demo is worth your time if it can answer at least one of these:
- Is the main mechanic still fun once the tutorial's over?
- Does it run properly on a PC like mine?
- Can I read the text, and are the controls and accessibility options usable?
- Does it actually support controller, mouse and keyboard like the store page says?
- Does my progress carry over, or is it clearly throwaway?
- Is this demo the current game, or some ancient build?
If you're noting performance, write down your machine, your settings and the demo version. A preview build can help you decide without pretending to be a review.
How should I prepare?
Make three lists: games you're already following, genres you'd normally never touch, and one evening just for developers you've never heard of. Only install what you've got time and space for. Twenty downloaded demos turns into a chore. Four you actually play can change what you buy.
Before you start each demo, have a look at the store description and the release window. When you're done, write one sentence: buy, wishlist, follow or ignore, and why. Then delete the demos you've finished, so a load of temporary builds aren't clogging your SSD until Christmas.
The two-hour Next Fest plan
Instead of scrolling until every tile blurs into one, give yourself two hours and a bit of structure:
- Spend ten minutes picking six demos: two games you know, two genres you don't, and two total unknowns.
- Give each one twenty minutes, unless it hits a natural stopping point sooner.
- Note the controls, performance, one thing you liked and one question you've still got.
- Bail on a demo as soon as it's clear the core loop isn't for you. Free doesn't mean it's worth your evening.
- Finish with no more than three wishlists and one developer follow.
You come out with a shortlist worth going back to, and you haven't kidded yourself that six previews are six reviews.
Which YouTube videos are actually worth watching?
An official event trailer is good for explaining the festival. For individual games, go to the developers. A long, unlabelled montage is fairly useless, because you can't tell what build it is, who made it or when the game's out.
For each game on your shortlist, look for one of these:
- an official gameplay walkthrough from the developer;
- a recorded developer livestream with visible uncut play;
- a clearly labelled demo run on a stated PC;
- an accessibility or settings walkthrough, if those features are what you're deciding on.
Only bother with videos that help you decide. Check the developer's channel and the video's date, and notice whether the creator had sponsored access or just downloaded the public demo like everyone else.
What should my demo notes look like?
Not a percentage score. A few quick notes are enough: the build, your machine, what you played with, how long you played, any technical problems, the accessibility options, and which buying question the demo answered.
"Follow" can be a more useful verdict than "buy". It means the idea works, but price, length, requirements or the release date are still up in the air. It leaves room for the finished game to change.
Can I trust how a demo runs?
It'll show you stutter, input problems and what settings you get on your own machine. But it might be an older build, and performance can get better or worse before launch. Note the build date if you can see it, then compare against the final requirements later.
On a handheld, pay attention to text size, battery drain, button prompts and what happens when you suspend it. "It launched" is not the same as "it's nice to play on the sofa".
When should I actually buy a game I liked?
Not just because the demo was free and fun. Wait until the game has a price, a clear edition and enough evidence about how the finished version holds up.

Which 2027 games should I be following now?
Our 2027 PC release calendar has the confirmed dates and official trailers. Several big February games will already be out before June, so I think Next Fest is best used for the smaller games you might otherwise never find, not the year's biggest names all over again.
Frequently asked questions
Are Steam Next Fest demos free?
Yes. Demos taking part are free to download during the event. The finished games might be paid, free-to-play or not priced yet.
Do demos disappear after Next Fest?
Some stay up, and others get taken down or replaced. Unless the developer says otherwise, assume the event is your one guaranteed chance to play.
Does wishlisting buy or reserve a game?
No. A Steam wishlist just follows the game and can send you notifications. It's not a preorder, and it doesn't lock in a price or a release date.
