The most fun you'll have with this game is talking to the NPCs without having completed their quests. Here are some highlights:

N. Gin: Ah! So beautiful! It is the stuff dreams are made of if you dream about plutonium all the time. I certainly do!

Crunch: What's wrong with you fool? Should'a stayed in school. Don't know what number's bigger than another number. Become an accountant. Go on to bigger things. Instead, you a chump. A chump that can't count. Crunch needs the coins, and brush your teeth: looks like a checker board in there.

Also N. Gin: Wah I'm crying because... I'm not pretty! Please Crash, bring me something that will make me pretty.

Cortex: Crash. Can you help me out? I need power crystals for my weapon of mass... helping people.

I love N. Gin: I know your weakness Crash: Bullets!
