Boktai is sadly underrated and relatively unknown, even though it is the most awesome game ever. One reason why it's not so popular is because a lot of gamers are afraid of sunlight, which is a stupid reason to not buy the game. You can always buy a UV lamp, for goodness' sake. Losers.
However, if one goes to /v/ on 4chan and posts a picture from the game, almost everyone there will recognize it.
"BOKTAI, HECK YEAH!"
