well the game is not for free and not a really mmo but for what read it has online function and it looks very nice.

can't say all to much cuz i didn't play it yet.
as for what i found out it woll be 1200microsoft points for xbox and 15$ for PC

game is like puzzle quest but in Bejeweled twist style.
