Ds game reconmandations?

I was thinking about getting tamagotchi corner shop 2, but all my friends say it can get boring. Then I was thinking about getting sims 2, some of my friends like it, others HATE it. Also final fantasy look spretty cool, oh to many games!! Plz tell me a good game worth buying, I love animal crossing, my fave game. I have harvest moon, my sims, nintendogs, zelda phatom hou gl, pokemon diamnd, pokemon mystry dungeoun alot of mario games. Well there the types of games I like...But i love games like animal crossing, like life games.
