This is what someone should call a real classic game!
The game is simply amazing in almost every sence. You can do whatever you want as long as you stick to the story of the game, besides you can interact with almost any object or character in game, the people is great too because of their interaction.
I dint give it a 10 because well the controls are very complex but once you get used to them its very easy to play and well i cant say nothing about how challenging it is even at the beginning but it is, is very hard even more hard than its sequel Twinsen's Odyssey.
Thats All i have to say about this great game is a really high recommended game for all kind of players, remember that not because its old its bad. Graphics arent everything (but for that time this game exceeded)
