just finished it and I don't know what to think, I hate it as much as I love it, kinda predictable since whole last mission takes an obvious direction so you know from the very beginning how it will end but I won't spoil it, I'll wait until more people finish it ;)
As for technicals, I'm really disappointed TBH ... graphically there is little to none improvement over ME2, cover system works quite dumb and everything looks over contrasted - especially shadows are way to dark, in some places you can only see whole person black with only visible eyes ... looks kinda creepy. I love what Bioware did with sounds ! Music is also great (gotta love main piano theme which can be heard in various areas like escaping earth or final mission)
Characters seems to be the only thing that was improved, here I can agree with Shadowknight.
Normandy is now stupidly redone ... just look at the minimap of the CIC deck
how could they fit that wardroom there !?
Lighting is nice, ME2 Normandy was elegant, ME3 feels now more like military ship.
Locations are cool, skydomes sucks big time, they are clearly 512x512 maps...
I really like dynamic life onboard Normandy, team/crew mates now move from time to time throughot the ship so don;t expect Garrus to sit in main gun battery control room calibrating stuff all the time
there was even a joke in one of the dialogs about him calibrating weapons everytime we spoke to him in ME2, nice one :
I wonder how Bioware's gonna make a continuation of ME franchise after ME3
