It's a roundabout way, but it works.
I might have to do that for the girlfriend. She wants Civ 5 off Steam, but I don't want to pre-gift it to her before Christmas. But, I picked up Civ 4 Complete instead. I figured I'd let her try that first since it's more highly rated than Civ 5 and she's never palyed 4 before. If she still prefers Civ 5, I can always buy it for her post-Christmas
Now, on topic. I picked up Amnesia back during the Halloween sale for pretty cheap, mostly because it's Steam Play for my MacBook as well as my PC. I found it "creepy", I guess you could say, but I wasn't scared or shocked by it. I haven't played much in it, however, so it might get worse later on. It didn't quite give that mystery feel that the last series did.
I wish they'd make another Eternal Darkness game -- console or PC. THAT was a great horror game with the oddities of the insanity system after you come back to the present day.
