I decided to play Commandos (1998) and it worked as perfectly fine as it would on Windows. It required a fan patch to support higher resolution and 16:9, but that patch worked fine too. The only large issues I’ve experienced so far are with multiplayer. For example, The Finals hadn’t updated their version of Easy Anti-cheat to a version that supported Linux so it didn’t work for a while, but it does now. That might actually be the only game that was an issue for me, and now it isn’t.
