The Yi Ar Kung Fu NES Game
Here's a bit of the 90s kid. I remembered owning the Family Computer back then and I remembered this game by Konami. I thought this game actually ended but it never did. The game has the protagonist Lee (presumably based on Bruce Lee) fighting five bosses. He fights one boss per round where he goes against Wang, Tao, Chen, Lang and Mu. Once Mu is defeated, the challenge starts all over again which is nothing more than trying to gain the highest score you can before you're inevitably defeated for good.
