A kick-ass series of games for GBA that use sunlight to incinerate vampires and ghouls. There is a solar sensor included in the cartridge that gathers sunshine from real world and transforms it into power within the online game.Boktai is sadly underrated and fairly unidentified, although it is one of awesome online game ever before. One reason why it isn't so popular is basically because some gamers are afraid of sunlight, which is a stupid reason to not buy the online game. You can always get a UV lamp, for goodness' sake. Losers.However, if a person goes to /v/ on 4chan and articles a photo from the game, everyone there'll recognize it.
