What was the longest and hardest game you played?

[masschamber]

hardest good game, probably the nes ninja gaiden
bad games seem to get stupid hard, the previously mentioned nes dragon's lair is insanely hard, you actually have to walk in sync with moving platforms or you'll fall off, and if one pixel of dirk's foot past the edge of a surface he'll die, as he can't jump or turn around with out falling,
longest, probably the complete shining force 3, each scenario is around 35 hours so around 105 hours to complete the entire game
