but I hope people don't forget to buy Ultimate on 3DS as well since it has the advantage of playing anywhere you go.
Yeah, this really concerns me. Going by this thread, it's as if there's no hype for the 3DS version at all. I really want the portable version to succeed because there's a lot us who really enjoy portable MH.
I bought a 3DS just for this (and Etrian 4), so I'm very excited for the 3DS version. If I ever get a Wii U I'll get that version too and take advantage of the crossplay. But for now I want that 3DS version.
