Ninja gaiden (1 and 2) on hard or higher difficulty.
Let's just run down this street, ooh ninjas! BOOM exploding kunai everywhere. No sweat, let me just jump over here *gets hit by more exploding kunai in the air* FUCK YOU I'm gonna run away, oh wait are that ninjas with automatic rocket launchers?
Also:
Hi! I'm a dog, you can't stun or stop me.
Hi! I'm a mecha, sorry where you hitting me? I couldn't feel it through my steel armor plating.
Hi! I'm a dog, but this time I'm a demon... Also, I have exploding kunai.
Hi! I'm a ghost fish, I will bite you now for 1% damage per second! Also, here are my 27 friends.
Hi! I'm a meteor crashing down on your face. Let me just get up with my big exoskeleton armored body while I hit you with my collosal two handed blade. Ouch! You broke my armor

let me just enter demon mode and add fire damage to my blade while I shoot fire and lasers everywhere. Did I mention there are 2 of us?
Hi there big boss, your only weakspot is your face, let me just hit it, oh you grabbed me and you're doing 75% of my hp bar in 1 attack? Sure that's okay, ooh you're gonna do it twice in a row? Sure I can live through that... NOT!
Hi! I am the one who stole your sword. You can go ahead and attack me from your floating rock while I shoot lasers in all directions and angles. Once you've depleted my hp bar I will drop down and stay in the lava so you can't hit me!
and last but certainly not least:
HI IM THE FINAL BOSS LOL! I AM BIG AND STUPIT! AND YOU CANT HIT ME WITH YOUR SWORD SO YOU'RE GONNA HAVE TO USE YOUR..... BOW?!?!?!
BOW?BOWBOWBOWBOW!? what were they thinking, I dont wanna beat the final boss with a freaking bow ._.
One of my favorite games of all times :V (no sarcasm)
