Ironically, you don't need to play them all to know the story. For example, I played Tools Of Destruction, but not Quest For Booty, and then finished off with A Crack In Time. I basically skipped the game in the middle, and still had a really good grasp of what went on in A Crack In Time. It even explains in the beginning what you missed, so it's not too hard. If you're unsure, I say give it a rent.
