I really didn't need more games.
But Spiky dropped his silver DS a while back, shattering the hinge, and after he managed to wire it back together discovered that the wireless receptor seems to be kaput, so in order to keep playing 2-player games we needed a new DS. And in the process of finding one for sale locally, discovered someone selling a stack of pretty decent DS titles for $10 each.
So now I have:
Chrono Trigger (I played a little bit of this once a loooong time ago but never finished it)
Castlevania: Order of Ecclesia (Oddly I'm not sure I've ever actually played a Castlevania game)
Mario & Luigi Bowser's Inside Story (I played the last entry in this series and had fun with it)
KORG DS-10 Plus (... I don't actually know what I'm going to do with this, BUT IT'S AWESOME and I couldn't resist the price.)
