I've not seen any new information from Bioware about new alien races appearing in Mass Effect 3. Forget about the dreaded "M" word thats took over the forum for a moment and lets talk about the important thing that makes Mass Effect truly great and thats its universe and story.
We've read small snippets about the newly introduced bird race known as the Raloi, but I want a hell of alot more new races. There's billions of ideas Bioware could use for creating new aliens e.g. Insects, fish, plants etc etc.
There could be loads of side missions for Shepard to do, like going through new unexplored Mass Relays and rallying new race allies.
Any ideas anyone?
