If college taught us anything, it's that there's always time for games. And when there are games, there is always room for some friendly FckInc competition!
Post your high scores, best times, greatest accomplishments, etc. (ideally keeping a history of old times for posterity, and even background information about the accomplishment if available). If the game is shareable, provide a link or some method of "acquiring" it. If the game is breakable, explain why or how (unless it's meant to be an exercise to the reader!). Ideally the game should be something that anybody can beat in a (relatively) short period of time, but huge games are also fair game if you managed to do something really crazy.
The following games either should be added because we definitely have scores for them, or because they're fun/challenging and would be good to have here:
