RPG's are amongst my favorite, though I'd love to see more futuristic/dystopian themed RPG's like Shadowrun as opposed to more fantasy/mid-evil based ones. But that's just me...
...not that I don't love my Ultima's and all...
...oh man, if only classic Amiga had a port of Exult! Not sure if it could handle it though.
Either way, I'm glad to see you have the interest in developing for AGA Amigas!!!
