GungHo Entertainment may have made the longest PSP demo to date. Ragnarok: The Imperial Princess of Light and Dark – The First Ending Version actually lets players complete one cycle of the game.

Of course, the full game has more than one ending. Ragnarok: The Imperial Princess of Light and Dark lets players see different sides of the story through the A.I.Z. (alternate if zapping) system. While the game is rooted in mythology from the popular MMORPG, Ragnarok for PSP is a strategy RPG.

Curious? You can get the demo without even signing on to PlayStation Network too. Here’s a link to the 263 MB file.

Ragnarok: The Imperial Princess of Light and Dark comes out on October 27 in Japan. As of now, the title has not been announced for North America.
