If you like pinball, you may be interested in "Future Pinball," which is a free pinball editor/simulator for PC. There are quite a few tables available, some of them outstanding, and some of them re-creations of actual pinball machines. Or if you are so inclined, you can create your own. http://www.futurepinball.com/
Bah. Pinball is not played on a computer. Unless they make a computer about the size of a man, with four legs and a steel ball rolling around in it, you cannot play pinball on a computer. How do you properly TILT a computer?
Suit yourself. I only mention it because it is free and is a reasonable approximation of pinball. I enjoy it very much on that level.
