I mean they have from Pole Position to long games like Dragon Spirit and The Tower of Druaga.

Whats the point in running any game? If you find enjoyment in it then isnt that the point? Does not matter what system or when it was made or how long its about having fun.

Yeah man, if you enjoy the game, and you're willing to invest time into running it, that's reason in itself.

If a game doesn't have a community of runners, you could start it!
