The ending..was an ending I suppose. Very anti-climatic, but I sort of expected that once you see Corypheus is the big baddie. Everything going on in the DA world cannot be attributed to him, so figured it would be a bit more DA2/ME2ish in that respect. (Pertinent to story but not progressing the main plot much.)
Also, a little disappointed you couldn't do anything too crazy. Did choices matter at the end? I couldn't see a way that it would have gone differently, but I assume the choices might be more relevant in another game.
I WILL say the reveals they do towards the end and after the epilogue were crazy. Flemeth's reveal was really cool, and really gave you more insight to her, but the stuff she says is so damn cryptic! And Solas being the Dread Wolf? Wtf! I have no idea what really happened there; Solas got the old god soul, for...?
Anyways, while the ending was anything crazy, I really loved how I got there. It's absolutely insane to think that basically they destroy the majority of accepted DA lore in the last few quests.
I hope this means we get a real expansion akin to Awakening instead of just a slew of shitty DLC.
