I'd just be happy if they supported it like the Wii. Seemed like they just dumped a ton of classic and new IPs out on the Wii. I didn't even truly realize how much they supported it until now. Sure the end of the Wii wasn't good support but they hit their stride at start and middle. They had a very good mix of almost all the gaming genres.
There was about 3-4 games released every week or so on the VC and there was a good amount of systems and third party games on Wii VC. Perhaps the Wii U eshop VC support is weak because the NX won't allow games to be transferred to the new systems like Sony and Microsoft did. Oh well... I can always fire up Wii mode if needed.
I see potential with an unified eshop and game library. Just have to wait and see if they deliver.
