I only use my DS for the Pokémans, and possibly the odd game of Ouendan!. I had Animal Crossin, but stopped playing it. And I have Phoenix Wright, but finished it ages ago, and never bought the 2nd or 3rd game.
Now my DS is just gathering dust, since I don't play Pokémon that often.
It's the one I got opn the original release, a fat silver one. The silver is coming off and leaving it white, and the hinge is half broken, but it still works fine.
