Not really if you're looking for F2P. The problem with games like those is the lack of budget behind them. There are a few that are pretty adequate for the market, such as DC universe.
If you want good story, I'd suggest The Old Republic. The gameplay is pretty cookie-cutter MMO, though. I enjoy it but understand why others wouldn't.
If you're looking for gameplay Steam has the best of the best in F2P atm. Planetside 2 is a remarkably well put together shooter. For free to play, anyway. Just gotta research around, man. We all know of great games in our opinion, but we dunno how you like 'em.
