I am going to fan more on SNK.
The actually went bankrupt a while ago. And had to join with a company called Playmore. It was interesting at the time and they did it to save their IP, which payed off in the long run given Terry is in Smash.
They were most famous for their Neo Geo gaming system and the many great games they put on it.
I know them for Wind Jammers, KoF, Fatal Fury, Art of Fighting and Metal Slug, but that is not all they had.
They even had a game called Athena on the Nes. the interesting thing about SNK is that they did the whole dream fighers thing before most others as King of Fighters was them putting all their properties together in a fighting game.
