Gradius is one of the first great shooters of the modern era. In this game, you play as Vic Viper, a space fighter that would go on to get appearances in Zone of the Enders and mentions in the Metal Gear Solid games. Originally, this 1986 post was going to be Adventure Island for the NES. When I was a kid, a friend of mine and I played the first couple of worlds in that game and it was fun. We didn't stay with it too long because we had Marioes and Mega Men to get to. In any case, I was looking forward to revisiting it... but then I discovered firsthand that the game is almost impossible after the first few worlds. Seriously. It's harder than Ninja Gaiden. There is one particular level (7-1, I believe) that is flat-out un-passable due to some truly baffling level design. Given my desire to not have a heart attack, I defaulted to a game I'm more familiar with: Gradius. It won't be the last time a Konami game appears on this list, because Konami is awesome.
