First of all, the one- or two-shot of the FATE zombie-now-with-aliens RPG run by Rachel has turned into at least a mini-series with several more sessions to go.
Then, the other Rob in the group is planning on continuing the D&D campaign I started, with the same characters, but moving onto a whole different story arc.
Finally John is planning on running West End Games' Star Wars RPG once month.
This is a big shift in my gaming group's structure, which usually had a single GM running 2-3 times a month, each time with just some of the gaming group, to each GM only running once a month for most of the gaming group. The biggest issue is group consistency. When I was running a single campaign, people could game twice a month and the group wouldn't get that large. Now I feel it is likely that everyone will try to make every session, meaning larger numbers at the table.
More as this progresses....
