Well, I think that there is some interest in RPGs on the PSP. But while we wait for a from-scratch RPG, I thought I’d surf around and find a finished one to port over. Well, here is my first release of the OpenGladiator RPG which was formerly a commercial game, and in the last four years has become a credible GPLed game for SDL.
The PSP version is compatible with the PC game saves, and you can do almost anything in the PSP port except type in custom names for characters/game saves. Try it out and tell me what you think.
