It's hard to follow up Clubhouse Games, New Super Mario Bros., Mario Kart, Elite Beat Agents, etc. But there have been a few games this year that are a bit different.
This year, the games that I've bought are The New York Times Crosswords, SimCity DS, Picross DS, and Brain Age 2. That's probably it for me for the year.
It's still a good year, but it would have been a stellar year with F-Zero DS and Mario Tennis DS(wifi).
