As mentioned in my initial post, when I started worldbuilding I used a few ideas that I'd had in the back of my mind since the early 1990s. They were only vague ideas and certainly not something that could be turned in to a game world. In fact, the stories I'd written back then were more steampunk than what I'm currently running (though I think it was probably about another ten years since I'd first encounter the word steampunk). Generally the world I'm now running could be considered the ancient past of the (fragments of) stories I'd previously written. The world has a few basic concepts, some of which I won't go in to as the players don't know about them yet!
I'm more-or-less a novice GM/DM and shall use this blog to jot down a few notes about games I run (and possibly those I play in). Not sure exactly how much I'll write or even what I'll write, as I wouldn't want to give away any secrets that players may potentially see here. Hopefully I'll be able to keep it generic enough without giving anything away. I'll have to be careful about write-ups of adventures that I run as well, as the world I'm running will be persistent and following players could find out a bit more than they should be what previous PCs have gotten up to. Technically I first ran a game in the mid-1990s - that game was Games Workshop's Judge Dredd the Roleplaying Game, so I would have been a JM (Judge Master) rather than GM or DM, though it only went on for a few sessions.
