(Game Boy Advance; Konami; Everyone)
Gamers usually never see the light of day, but to play ''Boktai'' they'll have to make an exception: Charging the vampire-killing solar gun requires you to expose a tiny sensor on the cartridge to actual sunlight. (Sorry, shining a flashlight is about as effective as garlic against Dracula.) In some cases, only direct rays will get the job done right -- a bummer if it's a cloudy day. On the other hand, at least it's impossible to stay up all night playing this game. (Unless you live in Alaska.) SPF 50 lotion not included.
