If anyone has good ideas for another tier ("if you get to 2000 bucks, you have to livestream yourself eating a worm!!" or something), I'm always willing to reach for the stars in a stretch goal.
As for the current goal tier: I have some ideas and plans for games to get jumping on, but my suspicion is that everyone reading this has their ears open for news of developers that might consider Linux ports of their games and never went further with it. Someone out there is surely keeping a spreadsheet already. If there's a developer that you think would be interested in getting a Linux port done by a guy that they don't have to pay, let me know. Hell, let them know about me! Let's see if we can get some conversations going with some developers that are sitting on the fence!
