GURPS is an amazing role playing system, i'm sure you'll like.
Be sure to remember it's very important to keep things on a certain level of reality (GMs and players) to be able to achieve real entertainment. I played by different conditions and it really sucked.
And i'm not saying that it is forbidden, i have my good share of surreal campaigns and adventures, but it's important to feel you are really there with that exact universe in mind... It's either the player and the GM's responsibility.
