It ain't just Tera, either.

WoW is still going strong, a lot of people seem to like Rift and, crap, let's not forget SWTOR which already has somewhere to the tune of 2 million people signed up for and trying to get into the beta (myself and fiancee included...).

I hate to say it but if Yoshi-P pulls this one off, he should spend the rest of his life being hailed as a God among developers.
