Boktai/YMMV


 * The Scrappy: Trinity, as seen (or not) in Shinbok. His entire task is to follow Django around, inadvertently causing chaos as he goes, and forcing the player to bail him out. Needless to say, he is pretty much universally reviled within the fandom.
 * Waggle: Unless you live in Hawaii or something you're going to have to waste a lot of time setting up lamps in order to play the game properly. Even then, you may want to apply sunscreen. Lots of sunscreen.
 * ROMs for computer emulators get around the distinct lack of a sunlight sensor (or the inability of your average computer to go out in the sun on a reliable basis) by being modified with a script that allows you to manually choose how much sunlight the game thinks it's nonexistant sensor is getting. This sadly breaks both the Sun Bank and the Astro lens, though.
