Controls and gunplay feel a lot better, seems a lot more fluid, something that has gotten better with every release (going back to ME1 now is painful).
I'm hoping that since its the demo they've skipped a few cutscenes and conversations, as as it stands its pretty much:
Knock Knock
Who's Th....
ITS THE REAPERS AND WE ALREADY OUTSIDE SMASHING YOU TO BITS
For what should've been a real dramatic moment, they were just sort of thrown in there in a sort of 'Deal with it' sort of way.
Mass Effect 1 is my favourite game of the generation, heck maybe even all time, and although ME2 did bring some improvements in gameplay, I felt the story and everything they setup in ME1 took a backwards step. I really like the characters they introduced in ME2 and I hope that they all return (except Jack) to help me finish the fight, but I'm hoping that the story is something worthy of what they began in ME1.
Roll on March 9th.
