The game itself was revolutionary.
So I'm redoing it all, first off this game was a stepping stone for other games to be built upon to which we now have more freedom to play in them. Its more than just a predestined path now and some games allow you to kill random doodads like birds flying around.
This game was fun and great, with a story to keep you entertained for a long time. The gameplay was brilliant, the graphics now aren't so great but compared with games of its time it was an improvement. The sounds and surroundings bring you into the game. The value now is pretty cheap and affordable, any computer can run it :D
It had many puzzles and side quests to do that keeps you on the ball.
