So my life got very interesting for a while, and just was barely up to playing let alone GMing. I have now gotten life under control, and want to start GMing again - but not sure the systems I GMed before are even popular anymore. So the games I have either GMed before, or have an interest in GMing in the future tend to be D20 systems or the like:
Monte Cook's Arcana Evolved
Pathfinder 1E
DnD 3.5
AD&D 2E
At this point I will be using modules, possibly adapted from other systems. There may be some other systems as well, like Mutants and Masterminds, and the Cinematic Unisystem I might be willing to try as well.
My playing choices are wider, but given there don't seem a lot of open games at the moment, not really thinking about them at the moment.
