Twin Snake was a horrible remade IMO. The music was better in MGS with melody music which fit the atmosphere of the game. In Twin Snake, they changed some of the music to techno-ish music. Also they remove Sniper wolf's ending music Enclosure!!
MGS just seemed to create a better atmosphere than TTS.
I hate how they changed Snake. Snake was calm in MGS but in Twin Snake, he goes berserk when the Armstech president forgot merly's codec #. Then pulls his gun on the Armstech President..... Which was stupid.
Some of the dialouge that were changed was better in MGS too IMO.
MGS:
Snake: Liar! That nervous glance... that scared look in your eyes. They're rookie's eyes if I ever saw them. You've never shot a person, am I right?
TTS:
Snake: Liar! Your eyes wander. There's no confidence in them. The eyes of a rookie, You've never shot a person, have you?
Silicon Knights killed a lot of the key moments with his ridiculous jumps and crap. Added a ton of Matrix-like moves that just ruined the feel of the game.
Twin Snakes took a great game and ruined it.
