Actiga is offering cool controllers for computers that include built in games. The games, dubbed Mini-Motion, sell for $20, and come in versions like skateboarding, RC cars, baseball, and more. Each game has a USB controller that is suited for the game, and the price is not bad. The games are compatible with Mac and PC (so even those two guys on the PC/MAC commercials can play together.)
Personally I would like to see some really rad mini games, such as a wicked compiler button where the object of the game is to make the project build and link without upending, but I am not sure if many could handle the stress of such an intense game…
