It must be the touch of ADD? Maybe.. I dunno. I bounce back and forth between creating my own modules, running purchased modules (and possibly tinkering with them), and a variety of systems, I currently have Advanced Fighting Fantasy, Blueholme, Basic Fantasy, Ad&D 2ed, and I'm considering grabbing B?X on friday. ARGH!
Not to mention I've printed off a half a dozen tree's in the last few months, and 90% of it, I probably wouldn't run so much as I've got some good ideas from (which is great).
Its maddening isn't it?
