Steam Next Fest can be a hectic time. While some of the demos will remain after the week-long Festival of Nextival is over, many do not. You need to find time to squeeze everything in—especially if you want to get in on a multiplayer beta of strictly limited duration—even if one of the biggest games of the year happens to be launching right in the middle of it.
There are usually three Next Fests per year, in February, June, and October, and 2025's first is wrapping up at 10 am PT on March 3. Based on Steam's own ranking of the top demos, organized by daily user count, we can see that multiplayer robot rumpus Mecha Break is number one and has been consistently for days. Which is interesting, given that it's currently got a user rating of Mostly Negative, with only 34% of the user reviews having nice things to say.
