Wow, the order is all wrong and many entries have better counterparts within their own series (no Days of Ruin or Order of Ecclesia? Come on now). That said, I'm glad Radiant Historia got on the list. It deserves the praise it gets. Bowser's Inside Story being on their is a good choice as well.
Something like this. Yeah there's a couple things on the GI list I don't agree with, but honestly it's pretty hard to come up with a DS top 15. DS has a ton of great games that are all about 8.5/10. Very few games on it are clearly above everything else - I would only name my top 5 as such.
3DS has a better group of AAA (quality) games in its first year than the DS' entire library. It doesn't look like it's going to have nearly the breadth of titles as DS though.
