1. Advance Wars - Dual Strike(Advance Wars is the only game I look out for at any Ninty conference)
2. Advance Wars - Days of Ruin(Once again can't wait for a new instalment)
3. All Phoenix Wright Games
4. Ouendan 2 (Just so much better than the 1st one)
5. Dragon Quest V
Notable Mentions: Mario Kart DS, Elite Beat Agents, Mario and Luigi Pit ( haven't gotten around to Inside Story yet), Locke's Quest, Phantom Hourglass, All the Castlevanias and yeah Picross DS ( so many hours consumed)
I actually didn't enjoy NSMB DS that much which is weird since I'm the biggest 2d mario fan. However, I can already tell that NSMB Wii will be my GOTY.
