hardest game you never beat?

[Super Buu]

Viewtiful Joe 1

I had to cheat to actually beat it. It was worth it, though.

Shame, go back and do it again. It's way more satisfying that way. It's kind of God Hand-ish in that it throws impossible odds at you, but the fun is actually becoming really good at the game, so that you feel like a god by the end of it.

For me ... the original Metroid. It frustrates the hell out of me. I hate spending ages collecting enough health to continue (when you load, you start with a miniscule amount of health) only to have it taken away by accidentally touching an enemy for more than a second. NES games are way too punishing.
