I just bought a license for The World of Goo, a great Linux (and Windows and Mac) game where you connect the goo balls to get them through a pipe. Sounds stupid but it’s great fun and the graphics is amazing. Just think of Oilcap or Pipemania from the old days, but with nice 3d graphics and funny goo balls flying around.And yes, you can pay as much or as little as you want for The World of Goo if you purchase it until October 19th. It’s a present from the authors for the game’s 1st anniversary. Here is a demo: I’m going back playing – it’s addictive!
