I have no idea what Etrian Odyssey Nexus is (some JRPG I assume?)
So I'll go along with everyone and say 80. So far I'm very low in the standings, not looking good.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
