First Game Jitters

Running my first game on wednesday, using Reign in the default setting (with a teensy bit of license taken due to vagueness in the setting). It's just a short, 2-session scenario, with only 3 players, but I'm still cacking it. My 3 players are all seasoned GM's and players themselves, so although they are good friends of mine and will no doubt be helpful and gentle with me, I have not had performance anxiety like this for a long time!

I've done some solid prep. Got my basic plot sorted, my 3 pre-gens done, NPCs and generic splods written up, time set aside for running in circles of terror beforehand etc.

Will try to update after tomorrow's game, wish me luck!
