Grand Theft Auto is a massive franchise for Take-Two Interactive. Don't expect it to become a massive multiplayer franchise, though. Take-Two Chairman Strauss Zelnick is less than enthusiastic about his company making a foray into that genre.

"We haven’t announced any MMOs. Competing in that market in the U.S. is a real risk," Zelnick told VentureBeat "It requires a huge upfront investment. It requires a big marketing push. And there are only two successful MMOs that matter in the U.S. It’s very hard to do."

A successful MMO is an alluring concept - who wouldn't like to be paid over and over each month for the same game? There's no denying the substantial risks, though. I'm curious which MMO Zelnick's talking about when he says there's two that matter in the US - whichever one it is, it's peanuts compared to WoW.
