Not entirely true, some games that are labelled "PSN Game" have a physical release, I know for sure that Pure Pool does.
That means that select physical games aren't included either then. Only "full games" are located in that ratio.
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.
