You know how trilogies typically work. You like the first one, but then you have to wait for what seems like forever for the next installment. BioWare plans to change all that by releasing world-expanding content for their new RPG Mass Effect via Xbox Live.

Mass Effect was first unveiled as the first in a trilogy of sc-fi epics at last year's X05. But with additional episodic-style content for the game, linking and expanding storylines between major releases, available via Xbox Live, the game takes on a whole new dimension.

Bioware's joint-CEO Ray Muzyka revealed at GDC, "With Mass Effect, the 360 game, we're planning on extensive post-release content bridging between storylines, bridging the gap between products".

While we've heard before that BioWare will support Mass Effect with release of "premium" downloadable Xbox Live content, this move puts Mass Effect on the cutting edge of the future of digital distribution.
