I know people don't really like these, but I just bought my first Microsoft points and am trying to figure out what to do with them (I got a 1600 point card). I already rules out worthless crap like Avatar accessories and themes/pics. Of the games I own, the only DLC I could see myself liking is the Crackdown one (that adds several new vehicles, a new weapon, new game type, and new Achievements).
I am almost certain to get games though. I was thinking maybe Peggle since I played the PSN demo and really loved it, which would take care of 800 points (I might get the Peggle Nights expansion later). The other 800 I was thinking maybe some classic arcade games like Dig Dug, Smash TV, or Root Beer Tapper.
Any recommendations? I already have both XBLA discs Microsoft has released, so don't mention Pac-Man: Championship Edition, Uno, Feeding Frenzy, Boom Boom Rocket, Luxor 2, Bejeweled 2, Geometry Wars: Retro Evolved, Wik: Fable of Souls, Hardwood Backgammon, Outpost Koloki X, Texas Hold'em Poker. I also plan to get Sonic's Ultimate Genesis Collection, so no games included on that.
