*Sigh* ...It greatly saddens me that in this day and age "old men/ugly guys" is considered a pro. But hey, I bet a lot of people would say the same if I inserted some of my kinks/fetishes as a pro for some games.
Now about the almost killing off Rebecca stuff... well yeah, that would have probably been the end of my time enjoying this game. I already have to wade through the sea of creeps, old men, and ugly bastards in this story. So killing off the girlfriends sister out of nowhere, probably would have sucked out any enthusiasm and enjoyment I have for the game.
If there's a scene that dark, but it's avoidable, I would be fine with it. It's okay to have dark stuff, even unavoidable dark stuff, but some stuff you have to be careful with. Again, I'm okay with whatever direction Bobby wants to go with the story and characters, I support devs making their games the way they want. That doesn't mean I'll stick around for it forever though, sometimes if I stop enjoying a game too much, there comes a time where I have to make a decision to move on sadly.
