The Pinball Arcade should be out on Steam shortly, and it's a really good commercial pinball emulator. Visual Pinball is a free pinball emulator and has some great tables, but it can take a lot of work to get all the pieces together.

Hey, as the master of games (and arcade machines in his house)... is there a decent pinball for pc to be had?

Ah darn, sorry I forgot that this was a shared account. I'll try and be more tactful in the future.
