the general concept of the plot so far 4 hours in is a bit irritating.
It seems instead of recruiting people, you're recruiting different races. Which is okay and all, if bioware hadn't used it in their past 3 previous games ME2, Dragon Age, and Dragon Age 2. I'm a much bigger fan of Mass Effect 2 than 1. But I liked that the story was the driving force, rather than "impending doom" must gather resources!
that said, the characters seem great, and the music is pretty damn good, minus those kind of annoying big bassy booms every time the reapers show up.
The combat and cover seems to have some minor improvements. I wish they improved the cover system a bit more, deus ex's is still quite a bit more responsive.
I imagine things will be more varied and difficult, because for the most part, I just got a shotgun, and nothing else, and my charge/warped is maxed, so I just charge everything and the cooldowns really quick. My warp is like a 1 sec cooldown. And have my party members use their abilities.
I'm playing in insanity so I imagine it gets more hard.
