Multiplayer Dragon Age?
Now, if they did do a separate (outside of the main game series) MMORPG or something, that might actually be cool. Assuming they could come up with a new combat system for it, better crafting, etc.
If however the next game in the series (and all the rest after) had forced multiplayer or something... please no.
I really don't think they'd do that though. So I'm not too worried, even if this isn't a rumor. But still, I'd rather in that case that they put the extra effort into the game itself, than trying to figure out how to fit multiplayer into it...
