Red Dead Redemption for PS3

OMFG this game goes forever.  Red Dead Redemption is a third-person shooter where you're the gristled cowboy with a dark past who's fighting to go straight.  The main story is hours and hours, the scenery reaches for miles, side quests with real stories are littered everywhere, you can collect pieces of outifts, or tame horses, or shoot horse thieves, or save damsels, or get robbed by damsels.  It's a jillion things to do, and you could easily spend a month finding all the hidden bits.

Also, pardon the "gee wiz," but whoever did the lighting for it deserves a medal -- sunrise and lightning storms were my favorite.  They really nailed the Western genre.  The music is similarly on target, though after a few hours I turned it down so I could run Pandora on a laptop.  It's a remarkably pretty game, making it good for spectators, too.  Yeehaw!

Braid for PS3 (PSN)

Braid poses a time-traveler's dilemma, what if you could go back and undo all your mistakes?  In this side-scrolling world, you can.  Biffed the timing on jumping those koopas?  Back up in time and get it right the next time.  Oh, but it's not that easy -- some things aren't affected by your time travel.  It makes for mind-warpingly interesting puzzles that involve overlapping, but not concurrent, time lines going in different directions.  Weird and wonderful!

Kometen for iPhone

I'm a sucker for playable art. You don't "play" Kometen so much as you kinda hang out with it, listen to groovy music, swing around the stars and generally just kinda "chill" with it.  Easy control, sweet music, seamless physics, lovely graphics and a whimsical story.  Holy crap, how did thirty minutes go by!?
