What is a good software where I can play all of my windows games on my mac?

I have seen a software called Crossover Games, but it only allows you to play a short list of games. I am looking for a software that can play any game.What is a good software where I can play all of my windows games on my mac?If you have OS 10.5 you simply need to get a copy of Windows XP and you can use Boot Camp to install windows on your mac. That way, you can install all of your games perfectly.
