While the gameplay isn't for everyone I think the yearly TI production can be pretty fun to watch with how excited the crowd and casters can get when the action happens. Valve has also done a good job keeping the native Linux client up to date, though the change to SDL3 had a few bumps Icculus was able to help get most of those sorted out now.
Dota 2 on Linux still have some small issues though, hope this get fixed in the Spring Cleaning
The stutter fest from a late-game Phantom Lancer?
