Actually, the Stern version does not have fewer fuel tanks. As a matter of fact, it actually has more because of the ones it has towards the end of the maze that are not present in the Konami version. The main difference is that on the Stern version, fuel runs out faster, so you can only afford to miss at most one (or sometimes two if you are lucky) fuel tank. Also, the rockets are slightly more aggressive in the Stern version.(posted 9455 days ago)Cheers, Ben Jos.
