I just bought this game the other day and it is fantastic, I'm about 5 hours in. Any other Mass Effect fans here?
I'm not really an RPG player, but I was getting bored with FPS all the time. I thoroughly enjoyed the Star Wars: Knights of the Old Republic series a few years ago and beat the first one six times. Bioware produces great RPGs.
Its a fantastic game, wish I had more freedom and more items were available though. The best RPG game I have played were either KOTOR or Freelancer. If you like bioware games, jade empire is really good too!
