- You wrote those games? Omega Race is *awesome*. Sadly I never got around to
- getting those C= paddles. The game plays so much better with a paddle. But it
- still rocks playing it with my trusty old Kempston Competition Pro. :)
-
- As for SargonII: The first chess-game I ever saw on any computer. Could never
- beat it except when I played with just the Kings and the Pawns (never was that
- good at chess, I just know how the pieces move :))
