Go back to Metacritic, and check their overall ranking of all DS games... here:
http://www.metacritic.com/games/ds/scores/
Start at the top (LoZ
H) and work your way down. There are a handful of games that I just simply missed for whatever reason, that are not perfect, but fun to play, the biggest example of this is a little puzzle game called Trioncube. But yeah, Metacritic does an aggregate of all reviews for a game, and thus, it's a pretty accurate view of what critics say overall about a particular game, dig down as far as you can, you might see some gems that people miss!
