Played the single player experience of the demo today for the first time, selected it as Roleplaying setting. I have to ask just what you're all bitching about when it comes to the fights? I played through it and apart from being a bit quicker and faster paced with the cover system and the melee being more advanced 90% of the combat plays exactly like ME2.

The two segments you play through is clearly: Part of the opening of the game and A side mission to secure Krogan and Turian support, probably something to do with Mordin curing the genophage to provide more Krogans when their race is dying out I could understand them being a little reluctant to enter in to an all out war against the Reapers knowing it could be their last war.

Both segments are picked to be action packed as possible, hence the massive amount of battle you face. It'd just not sell the game to the current market demographic if they showed 30 - 40 mins of mostly talking, exploring and maybe just 5 mins of combat.
