It’s a shooter with no aim assist, and the UI isn’t setup particularly well for controller (at least not yet)
Valve has manually selected the game to be run with proton experimental under linux, and it works on my linux desktop. So it will probably at least run on Deck, but I don’t imagine it’s a very controller-friendly game. I have no idea about Mac.
Comet has a list of supported requests on their github readme, and at least the achievement requests seem to be present. I’m not sure if Heroic utilizes them though
One of my main tools has been SteamDB’s instant search - it’s basically a giant list of all steam games, sorted by review score, with a TON of different filters you can apply. Looking specifically for something released this year? You can filter for it. Looking specifically for a co-op action shooter, or a singleplayer 2d platformer? You can filter for those too. Wanting to exclude early access games or exclude games with a min/max number of reviews? You can do that too. Very handy tool
Sonic & All Stars Racing Transformed Collection is a blast if you’re okay with a kart racer.
Flatout 2 is the OG combat racer.
If you’re looking for a true “racing sim” type game I would probably recommend one of the Assetto Corsa games, either the original or competizione.
CarX Drift Racing Online is probably not what you expect, but is really fun. Not exactly a traditional “racing” game because you don’t compete for time, but rather compete for “drift points,” with longer/wider drifts getting more score. It has a surprisingly thorough singleplayer mode, and the multiplayer is relatively relaxed. Multiplayer is setup in an open-world style; you join a big lobby and can just drive around with friends or randoms without actually competing for anything, although people in each lobby can start competitions that everyone else can opt-in to. The main reason I’m recommending it is it has very thorough car customization and is a chill, non-competitive driving game, whether that be singleplayer or multiplayer.
Don’t worry, Seth Evans (touring and studio musician for Black Midi) helped produce this song, and Black Midi’s drummer (Morgan Simpson) is credited on Greep’s new album, which is set to release in a month: https://open.spotify.com/prerelease/6uPLM4h3oBnZ3IKUL4f20H
Cameron Picton is also doing a solo project called CameraPicture or something
