Win the championship in first place.
Well, sure!
But the problem with Moto Roader is, there are seven different courses (each of which has eight different tracks, though the game calls them "heats" for some reason), and they're completely self-contained:
That said, the usual standard I've seen with games with multiple self-contained things -- e.g. the different campaigns in a wargame -- is that if you get a victory screen + credits with any of the individual scenarios, you've beaten the game. And I figure the credits are likely to be identical for every course (if not, someone let me know).
So behold, my victory on the Normal course! -- which, again, is really a set of eight different "heats" or tracks:
This next one is very blurry (cheap cell phone camera) but the image at top shows my racer popping champagne with a stupid grin on his face, while the bottom is the credits starting to roll:
So, is Moto Roader done now? (Or do I need to get seven identical credit sequences?
)
