Hitman 1 was awesome but I hated it half way through the game.
The Columbia drug mission is just fucking rambo-style. It's impossible to get through that mission steathily. I killed ALL of the house guards silently and piled them up into a room. The minute I went into the drug lord's room, I emptied two clips into him and he didn't die. He just ran around with his machine gun making lots of noise. By the time I got outside everyone was on my ass and I had to become rambo... BULLSHIT!
It's even worse in the missions after the hotel. By that point you can't even ATTEMPT to be stealthy. There's this mission where you have to get past 2 consecutive gates, and there's only one way through - right where there are guards. Even if you kill one and dress up as them, they still notice you and you get shot at. After you kill all of them, there are 20 more inside waiting. Really defeated the purpose of the game.
The Lee Hong mission and the Hotel mission were the best. I hope Hitman 2 is more like that throughout the whole game. I just bought (yes, bought) Mafia (awesome game). Will probably get Hitman 2 sometime in the future.
