Wow, just beat the game... read a bit of this thread, its interesting how different the game is based on the default world. I had to choose between Stroud and Hawke, and Kieran didn't exist so that whole sub story never even happened in my game.
The ending was a bit disappointing to me tbh, but that might be because I rushed to finish it starting with the Temple of Mythal. But defeating Corypheus just seemed kinda anti-climactic. I was expecting the battle to trickle into the Fade again, to have to face off against Nightmare, to have the Golden City involved, and maybe some choice that would turn the Inquisitor into a God or something, since that was hinted at a lot. Instead I drank from a well and became Flemmeth's slave, which I thought "Hey, that could be cool in a sequel if Flemmeth uses the Inquisitor to do something bad and you have to stop him". But no, she's dead, so I guess we dodged that bullet. The Solas reveal was cool, but I'm not a huge fan of cliff hangers like that, and like I said I was expecting some kind of consequence to drinking from that well.
We also never found out for sure what that spirit was in the Fade that looked like Justinia. Was it actually Andraste / The Maker? She said to tell Leliana "I failed you too", which I thought could be a hint since Leliana always talks about how she fails the Maker. And what's going on with The Architect? I was sure he would show up but he never did.
I dunno, I feel like there's a lot of loose ends lying around. Maybe I didn't do enough side quests? I never finished the Hissing Wastes or explored some of the elven temples in the Emerald Graves. But I don't really have a desire to play any more. I guess it'll be good material for DLC, but I'm not a huge DLC fan... >.<
