Melbu Frahma said: I'll play test this home brew kingdom hearts game for you. I'm currently in the middle of trying to home brew a log horizon game myself. There is a Log Horizon RPG already (partially) translated, it can be found here . Not trying to diminish your efforts at creating something new, but Japan loves these kinds of things, and someone's already working on an attempt to bring it to American audiences. EvilChildren said: May I interest you in FATE or FATE Accelerated? Seconding these as better for a KH RPG than D&D. Kingdom Hearts is much more about story-telling, and narrative elements than grid-based tactical combat. Fate gives you solid combat options, based on character-driven options better than D&D does, and doesn't confine you to a specific 'class'.
