I'd like to add Mega Man RPG Prototype to the list. While it's fully playable and feels like a complete game, it's technically only about 10% complete(!). The game aims to have all classic series robot-masters in the game and playable, and so far it's only got about 30 of the 124 complete. A lot of of the mechanics are complete, as are a lot of the robots and abilities and battle fields, but looking at how much we have left... just wow. So yeah, only about 10%. :P
EDIT: After reading the response to this thread, I wonder if I should post the game here at all. The idea of making something different than run-jump-shoot appears to offend people on this board to the point where they'll write it off altogether if it's not a clone of the NES games. :S Oh well, I did what I could to shake up the classic formula and try something new and if someone likes it, awesome, if everyone else doesn't, then they're entitled to their opinion. :|
