So, during a discussion with some of my regular RP buddies we decided that a WW2 eraish RP would be a ton of fun, but to make things interesting we decided that it would be way cooler to make a completely different planet to play on. I, being slightly over enthusiastic, offered to GM the game, and thus invent an entire planet. The only unfortunate bit is that I AM TOTALLY CLUELESS, at least when it comes to anything even remotely artistic... such as drawing/creating maps. So I would love any suggestions that I could get about anything from the basics of starting a map, to any software that would help.
