importing games

quick question: Will 360 games from the UK work on a dutch 360?

I would assume all pal games work on all pal consoles.

I just want to be sure, because I ordered 20 games from amazone (UK)

There is only one version of pal....which is pal. You would have a problem if you had a pal system and were ordering nstc u/j games, as they are not all region free. For your purposes, you will be fine.

I order UK games for my Danish 360. And as far as i know Holland shares the same PAL games as the rest of us here in Europe.
