I found a complete copy for a buck last year and bought it. Spent about 10 minutes playing it. The graphics are horrible and show how far 3D gaming has progressed - think of all those early 3D sports games with the polygons. The players look like dolls and have jointy legs, etc.
Being a sports title with no demand, it's not worth much either. I sold my copy a couple months later for five bucks. But if you just want a rare game to say you have one, it might be worth the cheap price to you.
