What are some setpieces where the sheer coolness and manliness of it makes it even more memorable to you?
To me it'd be stage 4 in Contra 3:
>start off with a motorcycle chase against several hoverbikes and a tank
>rip apart the belly of a battleship piece by piece while driving under it
>grab onto the missile of a friendly helicopter while fighting a jetpack ninja with a grappling hook
>the missile you're hanging on to gets launched towards the stage boss, and you have to take out its shield while constantly jumping between missiles in mid-air as extra missiles come in from behind to serve as platforms while the boss is shooting at you
