I'm really surprised, but in searching I didn't turn up anything for this game. I know it's been out for a while, and I just got into Advance Wars 2 for the GBA, which I've owned for a LONG, LONG time but finally plugged in. AW2 is awesome, and I'm very curious about what changes were made for the DS version.
I still haven't picked up a DS, but it seems like just a matter of time before I do, and this game is definitely pushing me toward it quicker. Worthwhile?
