Let's begin with a simple yet fundamental part: the game mechanics. I have thought about this long and hard, changing my mind over and over again. Which brought me to the point of saying that it doesn't really matter what game mechanics I want to introduce as long as they remain on a level that I can handle. I went from card game, to isometric RPG, to isometric economy simulator, back to isometric RPG. So I guess that's where I'll end up.
