Before internet back then, I always curious why Street Fighter II games for Mega Drive / SNES were suddenly dissapeared in my country.
Years later I found out in the internet that turned out many games stores was warned by some agents of government.
They said the game was deemed forbidden.
The reason was turned out because of Zangief's stage.
It has hammer and sickle, symbol of communism on the floor.
It resembles The Communist Party of Indonesia's logo that was banned by Indonesian Government.
