I don't know who you romanced but that isn't how it's been for me at all. Cassandra barely responds to romance options until a cutscenes just blams outta nowhere
I'm exaggerating, what I really mean is that you kinda go from..."you're nice" to "we'll bang okay?" at speeds that seem a bit different than the feel of previous games.
My love affair with Alistair (well mine and probably a million other peoples) was a natural evolution of two people in close proximity to each other for a drawn out period of time who just happen to work well together personality wise...well least for me, even my male warden characters I had for chasing Morrigan so I'd have some kind of excuse to be involved in the OGB situation that I was sure would be relevant in future titles, I always was like totally bro love with Alistair, and my female wardens were extremely stabby about him when it came to giving him up to Morrigan for even one night.
Thing is that all was very natural, Alistair's character drew me in and really made me like him...and it wasn't just...hi you're the cute guy, lets get naked...it was a genuine case of he really grew on me and there was no situation in of which I could ever see myself turning a bad world state where I'd tossed Alistair out on his ass because I liked him...I genuinely liked him.
I don't feel like anyones really trying to be liked in DA:I or even just being themselves and growing on me slowly but surely. I keep getting told how great they are by they people that know them, but they're not making much of an effort to charm me either.
So far the only somewhat human moment I've gotten out of anyone was Cassandra's obsession with trashy literature. That was relatively cute, but from a writers stand point its almost too easy a joke to make. Ms. Serious Pants spends her time in the privy with tawdry tales? How droll. But other than that, so far...everyone feels like a character, they don't feel like real people yet.
I'm hardly done with the game though so perhaps things get super real eventually. But I'm also having a bit of an existential problem getting my head around the idea of a messianic figure that also goes on dates....though we are talking Theodosian messianic here which is a bit more blood and nudity than the traditional real world versions.
