I mean, people got pissed at Earthbound back in the day because it was on SNES and had NES (not even good NES) graphics. But that game is BOSS. Still one of the best JRPGs EVER to be released.
I think that years from now, when you look back, people will hold XBC in very high esteem because games that were great graphically, but meh gameplay wise wont look impressive anymore, while XBC will still be a great game.
