The QTEs were the most tedious part of the first one, but I think they got rid of them in 'Rise'. At least as far as I remember.
I think it was a very enjoyable trilogy on the whole since I'm a sucker for some pseudo-stealth gameplay. I much preferred the first two on the whole though. I completed both of those multiple times, but with the third I almost gave up 3/4 of the way through as I just wasn't enjoying it.
Camilla was a good casting choice on the whole, but my god the character was portrayed as exceptionally whiney and morally messed up at times. I can't remember if it was the second or third game, but there was a section she was complaining about the suffering of the native people, or evil people destroying things, or something like that. Then in the next breath she is going on strawberry floating rampage blowing things up left, right and centre
Excellent gameplay, passable stories.
