That's a very good idea. A proto game with nothing fancy will definitely help get things hammered out.
I recon if I wanted to get very simple I could stick the game on one big map, but that might be culling the chaos too much. ^_^
A comic about game making for game makers? 
Seriously, thank you, I will read the comic and absorb it's knowledge.
Mapping is my favorite, but I recon I'll have to save it for dessert and do the meaty bits of plotting and eventing first!
Thank you very much for the comic and advice!
