This is everything I can think of/remember doing when I run games without focusing on stuff like encounter tables and whatever - more the social aspect and prep rather than why a 2d6 bellcurve encounter table is superior or how to do a hexcrawl. I'll update it with anything good that gets suggested. Obviously everything is JUST MY OPINION but I'm not gonna type that out a whole bunch
maybe we can talk about those tools later
also everything is opinion when you think about it gang
I run for a group of friends online and have done for like 6 or 7 years, transitioning from IRL games due to geography and life.
Sessions are about 1.5 hours to 2 hours and mostly in the 'Old-School' tradition.
Most campaigns run for 1-2 years, some going on for 3.
I use a mix of improvisation for most details and prep for tactical and major structural elements.
This said, when I've run in-person one-shot games for longer with new people, the sessions have been fun and feedback good.
