I'm considering buying a Wii U Basic set, but I really do not want to attach external hard drive to the system. I know that it's little opionated, but still, if I would use only disk based games (say 10 at max) and would download about 10 SNES games from virtual console, would internal 3GB would be enough for saved games and possible patches?
As @fbueckert correctly mentioned that that's depend on particular games, I reformulate question a bit: what's the largest patch on Wii U so far (if patches are applied in stack then full patches stack size)?
