There is one game that in my mind has always stood out as the greatest, no it doesn't have mega poly counts, its not even 3D, no voice acting, but theres no game more perfect if you Adventure gamer in the 90's you know you love this classic [b][size=4]The Secret Of Monkey Island[/size][/b]. Its utter perfection to me then and still is one of the greatest games I have ever played, and still play on a bi-yearly basis.
A closed second is [size=4][b]Final Fantasy VIII[/b][/size], being the only real rpg that has 'pulled me into its world', I enjoy many RPG's none have ever managed to do this to the effect that FF8 did.
