ClaDun: This is an RPG! is a not-so-subtle 8-bit style RPG (duh) built exclusively for your PSP. The name ClaDun is a bit of a play on words, but also describes what the game is. Cla(ssic)Dun(geon) suggests the game is built similar to a dungeon crawler of old, mixed with the humor expected from newer games, and nicely tied together by quirky 8-bit animations.
