A lowly 26.
And I only played about a dozen of them. The rest I got right either through guesswork or general familiarity with the game's appearance. Nice to see Stunts featured; I played the heck out of that game. Had an eensy-weensy crush on Cherry Chassis, too.
The game had some fantastic features too: the very flexible track maker/editor, the multiple camera angles, the race replay feature. Plus, some neat cars; the Countach rocked!
