Seriously. Playing the demo revealed a little more info than I wanted, but at least I could tell a lot of dialogue options were intentionally omitted from it. I'm not sure how far you went into the demo, so I won't say anything else. There's someone in it that I wished I would've waited for though.
Haven't played the XBox version in a couple years, but I'm trying like HELL to get better at it on PC. It is fucking DIFFERENT man, I am a straight up terrible shot on PC. I'm sure I'll get better, but damn. I'm on the Noveria missions now, and I can't steer the mako to save my life. If you thought that fucking thing was bad on XBox, jesus god. The hacking screens are COMPLETELY different, totally different mini-games that bare no resemblance of the ones on the XBox ME1 version.
