Metal Gear Solid 4
Oh my god, finally. This is fucking amazing. I'm glad I replayed the old games recently, otherwise I'd have been clueless to a lot of the details in the story. This game is much deeper than the previous ones, and way more cinematic. Hideo Kojima is a fucking genius.
I'm afraid the game's going to end soon, although I'm just on act 2. So I'm goofing around a lot, trying stuff that I normally wouldn't. So far it's been really intense and fun, because of the crazy situations I'm getting into.
Oh, and I don't want to spoil the game for anyone who hasn't played it yet, but the part after having killed the first boss is one of the coolest parts of any Metal Gear game. Fuck, I don't want it to end.
