I loved seeing the characters live for the first time. I think they're gonna be an interesting bunch and they'll balance each other's opinion well. Can't wait to see how, as the Inquisitor, we can talk with them and make them see our point of view. But more in particular:
Cullen: Okay, I'm gonna sound like appearance is all that matters to me (which is not the case), but DAMN he's a hottie. Besides that, I like how he still believes in the Templars, even after all that's happened. I can't wait to see how that plays out (even more since I'm gonna play a Mage for my first playthrough). Gonna romance him for sure with one of my female characters eventually. We'll see, but I have hope for him now.
Josephine: What a beautiful woman with a charming personality. This is good. I was kind of unsure about her at first but I like her more and more. I think I'm gonna go with diplomatic options a lot more than expected. She looks like she's the most objective of the advisors. Interesting!
Leliana: I must say I'm biased: I always loved Leliana. My canon Female Mage Warden and her were BFFs, so I have a soft spot for her. Like many others said, though, she does look a bit more hardened, especially about mages. I hope I can make her see the good side of Mages with my first Inquisitor, though. I'm thrilled that she is part of this game in a more prominent way than she was in DA2.
Cassandra: I didn't really like Cassandra until the end of DA2 (and even at that point, it was kinda meh). Yes, she does look badass though. And I like her more and more. She's a strong woman alright and won't tolerate any bullsh*t. Not too sure about the Herald thing, though. She and I might not get along well at the beginning. But she's still a more interesting character than I thought she'd be.
So for me it was a very positive first look. Love the characters in general (as in not only those four, but all the companions as well) and I think this game's story and character development is gonna be AWESOME.
