Hideo Kojima's franchise that nobody knows (or at least talks about). Boktai plays like a Metal Gear game, with the most unique gimmick I've seen in a video game. You need to play using the sun, and I don't mean an in game sun, I mean the real sun. The game cartridge itself has a solar sensor on it which detects how much ultraviolet light is hitting it, meaning the stronger the sun in real life, the more power the cartridge will detect. How this works is that in the game, Django, the main character has a gun which uses the power of the Sun, and the more powerful the sun is in real life, the more powerful you are in game. Other than that, the game is pretty simple. Imagine Metal Gear, but instead of Snake you play as a Vampire Hunter, instead of nuclear mechs there are Vampires, and instead of soldiers there are undead. That is pretty much Boktai except the story and level design is not nearly as fleshed out as Metal Gear. Boktai is a charming stealth action game, but doesn't offer nearly as much depth as Metal Gear with it's really generic maze like level design and uninspired story. But nonetheless still a fun stealth game for what it is and points for it's unique gimmick.
