You're just outside the lair of the Big Bad who has tormented you throughout the game. He's destroyed your home town, sent wave after wave of enemies to try and destroy you, and may even have called you a couple nasty names. This is the battle you've been waiting for. You enter the room and... he summons a giant three-headed dragon and runs away. Okay, no problem, you'll take it down, then deal with the Big Bad. You slay the dragon and... what? Why are the credits rolling? Why didn't you get an epic battle with your archnemesis? Unfortunately, that villain just isn't going to be fought.
