It felt a little engineered to me though because "it hasn't happened yet" - what you were seeing was a possibility not an IN THE PRESENT threat. If they had made the consequences more immediate not "in two years Leliana will go FULL crazy not just 3/4 crazy and be tortured beyond recognition" to THIS IS GOING TO HAPPEN TOMORROW, I would've been way more invovled. Like, punched Fiona in her blessed taint-free babymaker for signing over the Mages to Tevinter and handed Alexius' ass to him in the damn tavern. Hell, if you pulled that and then the whole of Redcliffe turned out to already be infected with abominations and Tevinter magisters lying in wait to ambush you, and you had to fight your way out of a whole crazy ass village... 10/10 would chose every time. But that wasn't the case. FOR ME, present, in-the-moment, inevitable threats are simply more compelling dramatically.
I chose the Templar side because the struggle with an Envy demon through your own head feels so immediately desperate. The part I dislike is finding the veterans. That's just to slow you down from the boss fight, and gather some extra XP. I'd have cut that section, streamlined it to "find the lyrium next to the bloodied bust to Celine in the crazy room," and moved straight to the boss fight. The only thing I wish they had done was delve into your character's origin more to make that sequence more revealing about the protagonist.
I agree on principle of not having neat little cleaned up segments like that with no real impact on the story, but I still love it simply because it gives something that this game was seriously lacking due to Coryflora being so unimpressive later on, which is motivation. Without that segment, Cornflakes seems even more pathetic tbh.
But even just looking at it on its own merits, the drama there, the pain and all of that like Leliana said and to quote her (I can't believe I'm quoting this airhead, ugh)
"It was real. The pain, the suffering, it was real!"
I love anything that gives me motivation, which is why I loved playing cousland so much.
