CVG has a new interview with Bioware co-founders Ray Muzyka and Greg Zeschuk discussing some of the massive media work that went into their forthcoming RPG Mass Effect:

Speaking of voice talent, can you tell us about the actors you're using?

Greg Zeschuk: There's over a hundred I think. There 300 characters; it's pretty crazy in a good way.

How difficult has it been to make each world in the game different and distinct?

Greg Zeschuk: There was also a very long conceptual phase for the game. In other words we spent six to eight months in the beginning conceiving how things would look. A large amount of work was spent with the ground work and visuals, so if we did actually end up building it there was a real clear idea what the armour looks like, what the environments look like and what the monster look like.

I'm looking forward to seeing what these ex-KOTOR developers can do outside of the Star Wars license -- and with what we've seen of Mass Effect so far I'm pretty optimistic.
