My idea is similar to D&D (and most other RPG's) in that everyone playing get's a character, there is a game master, and there is really no "winning" in the traditional sense.
The thought is that the characters would be survivors of the zombie apocalypse, and their goal is to survive. They can do this however they wish, be it building a walled town, traveling in a caravan for however long, setting off on their own, demanding tributes from other towns (npc or otherwise), etc.
The main difference is the mechanic of resource gathering and movement at the RPG level. In dungeons in dragons until the characters are in the dungeon they just kind of describe what they are doing. However, this game would require that characters (and the game master) know where those characters are most of the game time. In addition, resource gathering come into play. For instance, if one wants to build a wooden wall for their town, it costs x amount of lumber. Well, they have to go out and get the lumber. So a way to measure time spent gathering a resource, resources gathered, and the like has to be present.
Am I getting too complicated? Or is this more of a game for an MMO?
Thanks guys!
I'm going to look into GURPS, Fudge, and some of the others your recommended and see if maybe I can just publish an RPG using those systems! I appreciate it!
