Probably Beam.NG drive for me. Highly rated driving/racing game on Steam, and I thought I'd like it because it's like Forza Horizon 4 or 5 but more realistic. Unfortunately, maybe I'm used to Forza but the controls are janky and the UI is clunky. The mods I've tried are fun for a few minutes but gimmicky.
Whenever I get the itch to drive a virtual car with my controller, I just fire up Forza Horizon 5.
Perhaps the game will come around to me down the line if I want more pure simulation or more fun with mods.
