22nd) Which RPGs are the easiest for you to run?
This again mostly comes down to familiarity for me, so once again I’m going with Cortex. More specifically Cortex Classic or Cortex Plus Action (such as Firefly) which are the two variants I’ve personally run. For both of them I could pick up the game and presuming I had a setting inspiration have characters ready to run in a few minutes. Especially Cortex Classic where I’d even be comfortable with characters being generated in play using the old ‘assign your stat when you first roll it’ approach.
The other reason for picking Cortex is that I know I can comfortably run it for players unfamiliar with the system. I’ve done so a number of times for both friends and at conventions. Having that level of system mastery means I can focus more on the game in front of me without getting tangled up by the mechanics.
