Besides the usual nes, snes, gba, etc.. Imagine if they added Gamecube, DS, and 3DS games as well. I think there's a huge market who would love to finally play Zelda a Link Between Worlds. The Switch has to much potential, I just hope Nintendo do some of the obvious things. They tend to try and get fancy but somethings are just that simple.
Open eShop, and drop like 50 games for each system. Bam, that will keep everyone busy until the next game comes out for the first year. Their first year isn't looking great but that's ok. Year 2 will be critical.
