The Sunday players,
If there is one problem or difficulty that I have with running Atlantis: The Second Age at this point, as I discovered on Friday night in that game session, it's using a playtest document to run the game with, as the rules are a bit less organised and a bit more untidy than I would like. To be honest, I suspect this partially has to do with the fact that I'm still learning the game mechanics as I'm running the game, so I guess that's making me feel somewhat apprehensive as well.
In the meantime, I've got to spend a bit of time this morning re-reading some of the rules and jotting a few notes for sample combats and the like.
