To me Day Of The Tentacle (DOTT) was the best game ever made. It represents the pinnacle of adventure gaming back in the genre's heyday. Chase it up, it is definetly a worthwile game and is something that i replay even now.

If you do own the game, try ScummVM. It allows you to play the lucasarts and other classics on todays machines. There are some nice graphics options that teaches an old game new tricks like looking a hellova lot better.

Have phun.
