I had issues playing in the past on different OS' for whatever reason...
I recently came back to try it on Ubuntu 12 on a laptop, and the game works great! The only problem, multiplayer does not, which really is disappointing.
What happens is this, nothing shows up on the server list, and when I do click on the button to make the list of servers playing show up, everything freezes for like a few minutes, my internet on the wifi AND seperate ethernet connected computer BOTH completely knock off line-
and then i'm back at that screen with no servers showing and waiting to reconnect to the wifi...
hopefully someone has an idea of whats happening would love to play online or at least better understand the issue
