i think the eshop games are different to the 3dsware, at least, from a GW perspectiveToo many to list but at the moment there are about 20 3DSWare titles/updates to games going around to access.
I really hope someone is reading this and dumps Mario & Donkey Kong:- Minis on the Move, it is a 3DSWare E-shop title just has not popped up yet which I find hard to believe I would of thought that would be one of the first E-Shop titles to dump in my mind
