Now that the new Brandish PSP game has been released (in Japan anyway) it might be a good time to check out earlier installments in this obscure puzzle/RPG series. The Japanese-only "Brandish 4" isn't nearly as weird or disorienting as the original (with its infamous "the world revolves around you" mechanic), but it's still a pretty tough game in which you're constantly trying to avoid traps while navigating a very labyrinthine dungeon. The "auto-move" system is rather neat, though, as it lets you transport your character automatically to a square you've already discovered.
(Note: There's no sound in this video because the external program needed to capture sound in Windows applications on my computer wouldn't recognize the game.)
