>is there any reason to buy hotas for one game?
Not usually, but it would be if you play it a ton. If you're interested in that type of game, it's probably worth it though.
>What else can I play it with
Not sure what else supports it, but I know DCS, War Thunder, and IL-2 all support HOTAS controls.
Star Wars Squadrons will too when it releases in a couple months if you want more space combat.
