Oh, a few other games:
Little King's Story is excellent. It's an RTS/RPG hybrid about a king who has to gather troops, build up his town and conquer the other kings while discovering what's causing the mysterious earthquakes plaguing the world. Highly recommended. GT Review written by yours truly (even though it says Ron wrote it, but whatevs) right
here.
If you haven't played
Dead Space: Extraction on an HD system and can get it for cheap, do so. It's an on-rails shooter with some truly shocking, impressive moments.
Sin & Punishment: Star Successor is excellent too. It's a cross between an on-rails shooter and an action game. It reminds me of the flying sections of Kid Icarus: Uprising without the attendant hand cramps.
Finally,
Zack & Wiki can be bought for super-cheap, usually less than $10. Yes, it has some Wiimote waggle in it, but even Yahtzee thought it was all right before he turned into a total Wii-hater.
