You've already got Uncharted on your list, so you're good. Get both, they're mind-blowing. Also, you may like Ratchet & Clank: Tools of Destruction. Not as serious as the other games on your list, but infinitely more fun.

This game is excellent. I was perfectly happy paying $35 for it. Nobody should pass this deal up!
Ace Attorney Investigations: Miles Edgeworth 2
This is actually a DS game, not a 3DS title. Layton vs. Ace Attorney is for 3DS, however.
