MAGIC CASTLE Which Was a PS1 Game, Is Now Finished and Released
Back in 1998, a small team of Japanese developers began working on a game for the original PlayStation called Magic Castle and it was then rejected by seven-game publishers, which included Sony. The team worked on the game for 8 months and you can even watch the VHS video that went along with the pitch for the game online. Well, one of the team members called PIROWO has started working on the game which is a 3D RPG.

Actually, you can download Magic Castle from Net Yaroze now, to play with everything set to go except 4-player support and a Japanese translation, but PIROWO is making it better and still working on the game. You will need a PS1 emulator to play the old/new game.
