Turrican came out in the early ninties. If you happened to be an avid gamer living in Europe back then with an Amiga or C64, you propably have heard of Turrican. Being developed by a german company it was more popular in Europe.
Anyway, it's best known for being a technical & graphical showcase. I'm just gonna quote Wikipedia here:
"Turrican became very popular due to its high technical achievements, demonstrating graphics which many did not believe to be possible on a C64."
While the home computer versions were awesome, I personally didn't like the console outings (Super/Mega Turrican, Turrican on Gameboy, …).
