Akshually all the Dragon Age trailers were full of quips and tonally different from the main game!
To be fair, quips are present even in
Dragon Age Origins, but the key word here is balance. Alistair, especially, was a quip machine, but the game also allowed his angst and vulnerabilities to surface the more you interacted with him. The humorous moments were offset by the fact that the world was fucked, and sometimes, you could only laugh because what else could you do?
This is true of
Dragon Age 2 as well, and yeah, I love that game, sue me. You can play Sarcastic Hawke that quipped barely seconds after a sibling died in front of your eyes... but here's the thing. While things here were nowhere as fucked as the previous game, Hawke's world was fucked. Home gone, sibling gone, and by the end of the game, he would have lost everything, even a potential lover, and his victory is hollow... and you have the option to kill this character off in a later game just to complete the tragic tale of this protagonist. Hawke being a pathological bag of sarcasm makes sense in a tragic way, because really, what else could they do?
Dragon Age: Inquisition is a soulless boring single player MMORPG and I couldn't even finish the DLCs or do a 100% playthrough because I was bored out of my mind but there was still some semblance of balance. Not much, but there: Cullen, Leiiana, Dorian, Vivienne are good examples of quipping just enough without going overboard. Iron Bull and Sera are horrible though - it's like Felicia Day's horrid Tallis had fucked James Gunn and given birth to these two abominations.
Can this latest game have some kind of balance? Who knows, but after the horrible dialogues that plague
Mass Effect: Andromeda and
Anthem, I am not holding my breath. I won't even play this game, to be honest, as let's be real:
Dragon Age is essentially a romance simulator these days, and none of the companions introduced look remotely like they'd look good naked. Can probably get a better experience with Candy.ai.
