Actually, the Digimon World games are for PS, PS2, GC, and Xbox. The DS games are Digimon Story. They're only Digimon World in America, because BoA thinks we're too stupid to identify the franchise with just the "Digimon" part, so they call them all Digimon World. So shows what you know.
IMO, the system is irrelevant, though. Bandai is perfectly capable of screwing up no matter what you give them to work with.
I wish they did the battles and the gameplay in general digimon world 3 style. btw yeah digimon championship wasn't even a ''story'' title and was still called digimon world championship. shows what BoA thinks about our intelligence
