Oh there's only one game on the eshop, to buy the premium version you buy it from the in-game store for $10. Kind of like how you buy dlc. But yeah no, I didn't buy the premium version yet, having full online multiplayer is cool so I'll play that for a bit and see if I think it's worth enough to get premium. I am really happy with how Nintendo is handling Free to Play though, glad there aren't any microtransactions.
