GURPS

Let's kick off some activity here with a question:

How much crunch do you, personally, like in your games?

Ultra Lite? Lite? Basic Set? Every book you can get your hands on?

Light on combat, heavy on skills? Vice-versa? Light overall with some aspects way more fleshed-out? Heavy overall with some aspects way more simplified? Are there specific mechanics you like to take full advantage of? Mechanics you like to gloss over?

No wrong answers, let's just get some discussion going
