When you are a legend in the making - such as Ayrton Senna - powered by a Japanese company - i.e. Honda - and a Japanese entertainment company - SEGA, that is - wants to exploit your ventures, why wouldn't you want a say in it? Like designing your own race tracks.Screw Gran Turismo, screw Hermann Tilke. You need a fast track made by the best driver ever lived. There's no physics involved, though, but hey - it's the early 90s.
SEGA was the king of the arcades and Senna was the emperor of race tracks.
In the earlier days of computing there wasn't too much to do to make something feel realistic - such as a simulator -, and no one took entertainment business too seriously to throw hardware at it, hence marketing departments solved the problem attaching attractive names to the products of the respective companies they represent.
Too many sports games came out with the generic title "John Doe's Representative Sport". It would be interesting to find out how much actual input these people had in developing said games, but let's not get ahead.
It may not look much, but in 1979 "Monaco GP" by SEGA was the game to hit the arcades for. Following the same gameplay as handheld games offer, you only had to dodge slower cars. The weather was occasionally changing, going from daylight to night and back, the game ran on a cycle. Never stopped, you just had to race as hard on the straight road as you could before your time ran out. Since the original cabinet did not use a CPU, it couldn't be ported, nevertheless it was cloned for the C64 as "Le Mans" and for the Atari 2600 by Activision as "Enduro" - now with a chase view instead an overhead one.
[*NOTE: If you think you were convinced by this lady from SEGA to give a try to "Monaco GP", I suggest you reconsider your decision by looking at this magnificent one for "Enduro": a Datsun 280ZX AND a Lancia Stratos on the same poster? Too good to be true.]
