Mega Man X

Mega Man X took the NES formula and reinvented it for 16-bit: X was more agile with wall jump, dash and secret armor. The first level — Highway Stage — is studied in game design courses: it teaches every mechanic without a single text tutorial. Defeated Mavericks influenced other boss stages. The rock soundtrack was adrenaline-pumping. The moment you get the secret Hadouken remains unforgettable.
