Can you import DS games or import and play imported Wii games? Do you have a hacked Wii or an R4? If you answer no to those, then you're pretty SoL because there's no Gundam games on Wii or DS, at least not in America.
First one I know off the top of my head is Super Robot Wars. The series is more than Gundam and includes all kinds of series from Getter Robo to Mazinger to GaoGaiGar to Evangelion to Gaiking to even Zoids now. It's a JP only series except for the one spinoff game here in the US which doesn't even include series-based units. Releasing the SRW series here in America is impossible since it would be a copyright nightmare.

Hear that? It's the sound of my heart breaking.
