After some searching, I found a solution involving editing config files and restarting a system service. lol - classic Linux. Anyway, that did work, though, so then I moved on to trying to play the game. It was a little sluggish which wasn't too surprising. Reduced graphics settings and it seemed like it'd be okay. Then the next problem hit - we simply could not get the Linux machine to talk with the other kid's stuff. Searched all over... I would always appear offline. Nothing worked.
