Mass Effect 3 while be here in March next year and an end to the commander Shepard Trilogy but not nesaceraly the series. I have heard some say there mite be more games based on the ME universe. If so what kind of game do you want.
Heres some I would like to see. (I may add more).
A game similar to star wars battlefront where you fight in great battles and wars you hear about in mass effect, such as the rachni wars and krogan rebelions. Imagein playing as a turian, sularian and asari as you fight the Krogan hord or the other way round. Or play as Geth or Humans at Eden Prime.
