A few games appeared on this new section of XBLA this week. I downloaded them all and played each for a bit this evening.
Culture:
Simple minigame with two WTF minigames.
Jellycar:
Good idea, far too hard to control.
Little Gamers:
Looks nice, plays like crap.
ProximityHD:
Decent multiplayer puzzley strategy game.
Rocketball:
Awful.
The Dishwasher:
Excellent, although loading after every screen? WHAT
TriLinea:
Meh.
