After the Aliens: Colonial Marines debacle, it's fairly difficult to get excited about a game set in the Alien universe, but I think it's slowly starting to happen for me. Each and every time I hear the team at Creative Assembly talk about Alien: Isolation I'm just like... these guys get it.
Quick disclaimer: I prefer Alien over Aliens. It's just my personal preference, and I've always wanted to play a game that focused on avoiding one supremely scary, overwhelmingly powerful enemy. So Alien: Isolation, which is attempting to do precisely those things, seems like a game tailor made for my tastes.
In short: this team is talking the talk. I can't help but get excited. Some of my favourite sequences in horror games have been about hiding from completely impossible to kill bosses. The sequence in Resident Evil 2 when the boss tanks through the wall, the unkillable dude in Dead Space. Those moments have stuck with me. Alien: Isolation looks like a game dedicated to those moments. So yeah, I'm excited.
