GameStar visited BioWare and interviewed Casey Hudson. Preview here.
They also gonna have the first review up next week.
Zat is of course written in German, but reading through it, ME3 might have the best C&C ever in any BioWare game, possible any RPG ever released. Like, Commander Shepard determining the fate of whole civilizations, depending on how prepared you are and how thorough you play the whole game, certain side missions might open or vanish again. There's definitely tons of replay value there.
Despite the crappy demo, tis is a must-buy anyway. If not for a great game, at least for some cool Shepard memes.
