REMATCH is basically Rocket League but actual Football, it's probably going to be quite popular and will be playable on Steam Deck / SteamOS.
One thing I was worried about was the anti-cheat (Easy Anti-Cheat) but it appears that will be enabled for Linux platforms at release. I did email both the publisher and developer previously multiple times, to talk about the anti-cheat situation and neither replied to GamingOnLinux. The previous Beta worked well and it's listed on our dedicated anti-cheat page.
As of today, Valve have officially tested and published their ratings for it to show it's Steam Deck Playable and SteamOS Compatible. Valve note that the launcher may require touchscreen, you need to manually bring up the on-screen keyboard and some text may be a bit too small on Steam Deck. All issues that should be easily solved by the developer.

More about it:
Teamwork, strategy and skill are at the core of Rematch. Set against a variety of virtual backdrops, Rematch brings forth the core essence of what it means to play football from the perspective of the player on the field.
The gameplay is designed for nonstop competitive play - there are no fouls, offsides or VAR. Control one player on the field for an intense showdown of 5v5, or choose from a variety of quickplay modes, evolving tactics and decisions to fit the moment-to-moment needs of the match.
Just like the beautiful game in real life, precision is everything.
