I'm an artist who have ended up more or less as a programmer. Right now I'm in the process of developing an isometric RPG tile editor. But being an artist I find story writing quite interesting.
I am trying to make the editor as usefull as possible ie. so it can be used for other types of isometric games, not only RPGs (maybe action/puzzle or adventure games). All I got right now is a pretty cool looking tile editor with shadow casting and things like that (no scripting yet though, I'm working on that).. As soon as I'm done with the editor I will go into the game design of the RPG that I hope to make :)
