Yeah, the game really was quite epic right up to the end. Which makes me sad as I really dont feel like playing through it again right now. My only gripe was the Lip Syncing, I found it to be quite terrible for the most part.
I think this is actually the first Bioware ending I haven't liked. ME1 and 2 both had very satisfying ends I thought, DAO I think I almost cried when my character had its funeral, DA2 for a rubbish game the ending was fine (unless you killed lelliana in the first game then it was just weird). KOTOR's (the original) was good.
But this, really there are no different endings, there are no satisfying answers, the ending I picked ended up really confusing me, I dont understand that kid at all. And the dreams were weird. I figured they were just to show Shepard's stress but they didnt do anything really.
Bioware I will PAY you another 20 (ontop of the 20 additional I paid for the CE) for a better ending as DLC. Appearantly theres a secret ending for NG+ but.... I'm not sure how much faith I am willing to put into that to be better.
apart from that, Shepard as a Vanguard with only a shotgun was very overpowered. Quite enjoyed that. Well until I ran into Banshees and Ravagers anyways. Dunno, but Brutes always went down fairly quickly for me in comparison to those 2.
