well, I'd like to think so. at least, the fact, that they were "raised" on games that look 10 times better than those I had played 20 years ago, doesn't necessarily mean they don't appreciate a good indie game or an RPG with subpar graphics.
New Vegas showed that people still buy complex games, that look dated just as willingly as they grab every single Medal of Honor game. and then there's WoW, that, in my opinion, looks terrible, but it doesn't stop people from playing it.
