If you're in the mood for a game that's about classic-style dungeons and is an RPG, you'll be delighted to hear that NIS America dated the PSP game Cladun: This is an RPG! The game will be available on PSN on September 21.

Cladun allows players to build their own tiny character sprites and take on randomly generated dungeons. It features ad-hoc play, so up to four players can wander around dungeons together (while wandering around together in real life). To see more of Cladun, you can browse around the game's website, which is designed to look and sound like the game. You can also play Cladun-themed picross. After all, if you like dungeon RPGs, you enjoy difficult games.
