Well, being the son of "captian crazy," yes, I do own some co-op games. Well my father accually. He owns a baseball theemed pinball game from the 50's (may be 60's, I'm not sure), but it is sort of odd. It's not like the traditional pinball games of today. I't has wooden sides, and instead of two flippers, it only has one. I believe this is because of the fact that it's baseball theemed, and the flipper is a baseball bat. The objective is like any other pinball game, to hit flywheels and such, and rack up points.
He also owns a duck-shoot game, which I find quite interesting. It has a glass top and front, and metal sides, bottom, and back. There is a grey aluminum gun fixed to the front, and the objective is to shoot ducks that pop up in the back. The "ammo" used to shoot the ducks are pennies you put in the gun. Each time you put in a penny and shoot, it despenses a gumball. It's just a countertop game, nothing electronic.
My dad's sort of a game/gumball machine nut. Each year there is an annual expo in Chigago, held in April and November we try to get to. We've only gone once, but it's a possibility we may get there this year. It's great fun. Plenty of games and machines, new and old. If you are honestly looking for a Skee-Ball machine, I suggest you try this place. They're easy to find, and are almost always in good condition, or are new, and are generally reasonably priced. I can give you the information if you'd like.
Any way, back on subject...Coasters, parks, coasters :).
