I haven't got many either! I recently got "Imagine: My Boutique" for Christmas...I picked it out cause I saw it on TV commercials and it looked neat. It's not too bad. But I can see me getting through it quite quickly and then maybe being bored. Lol. Um...I haven't got any Mario games! But I want them! I looked for Animal Crossing because I played that on my brother's....that's supposed to be a good one. But it's still so expensive here ($65!). Also, I have The Sims 2 for DS but it's a lot different to Sims on the computer...I think the computer one is definitely better. Brain Training is fun! I haven't tried Pokemon or Zelda but they both look interesting!
Right now, my fave game is the "Boutique" one cause you can create a bunch of different things like flower arrangements, perfumes, cakes, etc. But I definitely need to get some other ones! Lol. :)
