This game probably has the best story of any game EVER! Beyond that it is also a very good point-and-click adventure game.
I have the steam version and the game looks great if you force Edge-Detect Anti-Aliasing in the Catalyst Control Center, unfortunatly the mouse pointer gets buggy and ruins it, hopefully in this version this is fixed, even if it's not Nvidia user might have better luck.
I think the background images are pre-rendered so a lot of them look pretty great for a 8-9 year old game(even without AA), even if you can't use AA and have to play with a blocky April(like me) the game is well worth it definetly one of the BEST $10 I EVER SPENT!!!
