Graphics are often the least of my concerns, I still play NES games happily.
I've heard a bit about Runescape, but had no real desire to try it. I'm not too big on the idea of joining a MMO that's been out for multiple years either.
I meant start from the ground up on a well-established (2+ years) MMO. It could be done, but I'd prefer to be a part of the community from the beginning.
