Okay, I'm going to Pro/Con this thing.
PRO:
-It's challenging. There is never a point in the game that feels frustrating. Every goal in the game CAN be met... and you know it while you're playing it, but the difficulty of those goals is insanely high.
-It's scary. Not in that Silent Hill creepy kind of way... but the game throws so many surprises at you that you will jump out of your seat. I played through a lot of the game standing up.
-It has good replay value. You can go through the levels a variety of ways (but it's still linear... more on that in the cons) and the levels are all fun, so there's a lot of reason to keep this game around even after you've beaten it.
-Brian Cox. No more info is needed on that.
-There's a lot of levels. Tons of them. Many times it doesn't feel like the game will ever end. The levels are, for the most part, very well designed.
-The AI is fucking amazing. These are some of the smartest game characters I've ever seen. Also, the personalities of the gang thugs if hilarious. Listening to the things they say is fun.
-The stealth is fun, but the gun battles are SERIOUS fun. I'm usually the stealthy player... but I was loving using the firepower in this game.
-The control is great. Good camera. No real complaints there.
Okay, the Cons:
-While I love the levels, I was really hoping this game would be less linear. This is a weird complaint, as I love how the game feels like someone is controlling you... that's great. But still... I wish there were more ways to go about several levels. One early level in a junkyard I just didn't like at all. Way too linear and way too uninteresting.
-The game loses some steam about half way through. When you get into the real world and have to deal with cops and then Director's personal guard, the game loses some of that personality I talked about. You start off with these great gangs who are funny to be around who have tons of personality. Then, when you get to the real world, the characters become boring.
-The first third of the game can get tedious. I'd say when you're about 40% through the game, things get old fast. The pace quickens up around 50 or 60 % through, but still.
-The stealth kills, oh so hyped before the game came out, are boring. In fact, on several weapons, the tame kill is more cool than the gruesome kill. Basically, the stealth kill thing feels like a gimmick at times and can get pretty old.
-There is a point on the last few levels where I got REAL bored of stealth. I just said "fuck it" and went into every room blasting away. Don't get me wrong, the stealth in this game is great, but it can get old.
-They had more opportunities here. The missions where the Director sets you up with objectives are really, insanely fun... I wish there were more of them. The real world with the cops... bored me.
-While the control is good, I kept wanting to crouch and jump. Crouching would have come in very handy dozens of times. I wish you could do that.
-The reporter character bored me.
-The bonus stuff you earn, like most game bonus stuff, is none too interesting.
-The ending is kind of under whelming.
...
Well, that's the end of that. Great game... it gets the Cheese Biscuits seal of approval.
