I wholeheartedly disagree about the combat. I loved the combat in original trilogy (maybe except Mass Effect 1), I always picked the highest difficulty and each fight for me was like a semi-chess match. Constantly pausing stuff and choosing just the right ability, from the right teammate, on the right opponent. I loved it. This games just goes all out DOOM, and if I wanted to play DOOM, I'd go and install DOOM, I wanted Mass Effect. This combat was extremely boring and long, but then again, the guy playing sucked big time, that may be a factor too.
But combat is not that important, what is important is the story (which we know nothing of yet) and the characters, which - as this demo showed us - are extremely annoying and have voices and lines of a kids show like Franklin, it's horrendous. I'm seriously worried about ME:A if this is how the whole game is going to play out.
The hand-holding is also overstaying its welcome, all the time someone tells you what to do and why you should do it, BioWare seems to think that if they force player to think for more than one second, they make a mistake.
After watching this demo my hype level is low.
