I think there's a game inspired by BK being made. It's called Project Ukulele as far as I can tell.MY IDEA FOR A 3D PLATFORMER:
Years after you escaped Peach's castle and went through all the chambers to get cake, you return. It's totally overgrown and abandoned. You try to escape with Toad, but Peach ends up capturing you to make you complete more levels. However, you dethrone Peach and make Toad the king of Mushroom Kingdom. BUT THEN HE unexpectedly betrays you, and you have to work together with Peach to defeat him. Eventually, you send Toad into Super Mario Galaxy, and you're free to leave the castle.
My favorite line from V from Vendetta is: "Behind this mask there's not just flesh and bones and brains, but there's also another bulletproof mask, and bulletproof masks are bulletproof."
