Did anyone else get extremely bored with this game about 6 hours in? I absolutely loved the first few hours. I totally dug feeling like the Predator, going invisible, hopping around, and killing guys that never knew where I was. I also really liked how many options I had for killing guys. That said, about 6 hours in I was in my comfort zone and the game didn't ever make me leave it. I could go through any set of enemies with exactly the same tactics. I like the options, but I thought that they ultimately killed any tension or challenge or lasting excitement. Anyone else think this way?
