Renegade Shepard is such a space-asshole, I can never really play it that way. :) But I have fun watching the compilation videos of his expoits, like THIS.
Yeah, it's a rad game. Totally about "recruit these people" and then it's basically over. I'm proud to say I ended it without any crew members dying because I'm not a dick.
Final Fantasy 13 on the other hand is pretty friggen horrible. I'm gonna give it a little more time, but it is super boring and seemingly from a time that land forgot.
