10 Video Games That Blew Your Mind (Without You Realising)

What is and is not mind-blowing really depends on the context of the time period in which it came out. What seems utterly ordinary to a fellow of today would be utterly inconceivable back then.
Hence, the original Metroid.
Everyone talks about the revolutionary reveal of Samus Aran being a woman the entire time, but right at the beginning is something that made the game ground-breaking that people nowadays take for granted: going left instead of right. In side-scrolling platformers, this was completely unheard of.
Up until then, if an object left the screen, then that object ceased to exist. But Metroid - at the cost of the game's environments coming off a bit samey, maintained a massive (for the NES) ever-present world to explore. Thus laying the groundwork for multiple entire genres of gaming today.
