Friday, after hearing good things about it on the Gamers with Jobs podcast, I decided to give Castle Crashers a try. The art style, humor, and fun gameplay convinced me to buy it.
Meanwhile I kept trying to get Team Fortress 2 to run in Crossover Games Linux, but without success. I ran out of things to try, so I opened a support ticket with Codeweavers and sent them a debug log. I'm waiting to see how they respond.
