10 Classic Video Games You Didn’t Realise Had Sequels

10. Street Fighter II (Not That One)

What if I told you Street Fighter II wasn't the only sequel to the original beat-em-up? And we're not talking about the Champion Edition or Turbo. There is a completely separate follow-up to Street Fighter, which only a select few know of.

Street Fighter did so well at the arcades, it was ported to pretty much every system, many of which were converted by a company called Tiertex. Because Capcom took so long to release its successor, Tiertex cheekily decided to rush out their own sequel called Human Killing Machine before pitching it to Capcom. (If you think that's naughty, Tiertex did the same thing when they made a sequel to Strider, which was also created by Capcom.)

However, few people were won over by HKM, considering you could only choose one character and there was no two-player option. Instead of having distinctive combatants like Ryu, Ken, or Sagat, Human Killing Machine had the player face forgettable rivals, including a tray-bearing waiter, a matador, and a dog.

It was a huge relief Human Killing Machine did so badly, since it didn't take the spotlight away from Capcom when they released the official Street Fighter II, changing the gaming world forever.
