Will I am more attracted to Alex, physically, I really do like Isa too. I remember the first time playing, that first sex scene with Alex, I thought a lot of players would object to the forced relationship. And they did.
And I could see their point, even if it didn't bother me personally. I mostly thought 'The Dev is trying to tell a story here, let's see where it goes'. And, obviously, liking Alex from the start didn't hurt... There was another scene with, whatshername, the Journalist, that was forced and then quickly made optional. I didn't like that (i.e. it being forced), because in my mind I was with Alex then (even if it wasn't official yet) and it didn't really fit if I want to play as a good BF.
This very quickly became a game about a throuple (and the thriller story-line of course) for me, and the journey to that is really the aspect I am enjoying the most. And to make that feel realistic IMO, you really need to set it up and build it slowly. Which is what BTT is doing and pretty much all of us seem to be happy about. We are a subset of the wider AVN fanbase, if you like, and this is a game made for us.
I don't necsessarily meant the throuple path, but also the friendship paths.
