Turn Based RPG Flash Game

Hey everyone,

I’ve made a few Flash games in my time, tile based and not, and am wanting to advance to make a turn based RPG. I have pretty good knowledge of actionscript, but now I need some guidance. I want to make it somewhat like this.

If someone could just help me get started, I would appreciate it greatly. Thanks!

Anyone have a clue on how to get me started?
