I can't believe that I didn't think of Classic Doom first. Re-creating the original Doom experience with the new and sexy Doom 3 engine. A fair amount of my weekend has been sucked away into this, and I'm loving it. Not only does it revive my love of blowing up baddies by shooting explosive barrels, it also allows me to face my fear of imps in a familiar environment, so I can someday go back and play Doom 3, which is really scary, and I am still not allowed to play by my SO because she fears I'll have a heart attack with all the jumping I do playing it. Yes, I'm a total wimp BTW.
