Me and a bundle of folks have started playing games co-op or semi-co-op using various GM emulation resources like randomization tables and the Mythic system. Honestly it's been really eye-opening from a GM perspective, as well as a breath of fresh air that's helping offload some of the stress that GMing off the cuff often brings me.
For someone like me that has a lot of neuro's that make letting things go and taking control away from myself kind of difficult (OCD, Autism, Fleas), Improvisation directed on what the players are doing can be really difficult. It's often hard to let go of this idea "What I want to do will be really fun for everyone though! Isn't it it important that everyone listens to me then??" And that's something I think a lot of people who have this kind of neuro-cluster or people who have trauma baggage deal with a lot.
Co-operatively roleplaying, or co-GMing means that everyone at the table asks questions and has input on a given scene, and since all of their input is offloaded into a different thing then me it means that I get to watch their ideas flourish on their own and with a little spice of my input. It's pulled me a lot out of the chair and it's let me see first hand how things interract without my direct input.
BUT ALSO IT'S JUST REALLY FUN TO LET THINGS BE RANDOM?
It's not as chaotic as you think, the Mythic GM Emulator utilizes a set of matrixes based off of yes/no questions and then the players decide what the propable chances of something happening are together. We're leading a caravan around a rockey valley, what are the chances that the Banditos will be here? Aren't they based far away? Haven't they been reaching into other turfs lately? And questions like that build into both the matrix and also invite the players to answer why that could be. Things like motivations, action scenarios, and etc. are also accounted for in another matrix.
Our Shadowrun crew of supernatural-thing-hunters (we're kind of getting our footing here) were hired by a bookie who's gambling company recently found out that one of their clientel was a vampire who'd been using his magic and charm to participate in cheating, meaning that said vampires entire history of gambling is ill-earned, and thus factors entirely as debt. This strangely reclusive and paranoid vampire kept all of his holdings in his mansion which is loaded with security. Not an issue since the gambling den can just pay off someone to nix power to his mansion. But recently the guy got axed by cultists who bound his spirit to the site, meaning that the mansion is now haunted by THE GHOST OF A SOURCEROUSLY POWERFUL VAMPIRE
Breaking in wasn't very hard at all, the only people watching the house were a bunch of beat cops who got asked to make sure nobody is squatting or going inside, the house became viral after a group of ameture ghost hunters livestreamed an incursion into the building, during which they all got nixed by the terrifying spirit drawing tons of other goons to the location.
We're not ametures though, so we get in and are greated by either one of the houses former servants, or the concept of a servent of the house. Hard to tell, spirits are weird. We asked a few questions, and then asked if we could be led to the master of the houses bedroom, which was a courtesy we were given. We rolled in Mythic to see what the spirits intentions would be and got "Decieve, Safety" which we interpreted as the spirit is trying to keep us safe by locking us in a completely different room. And since it was a spirit that did it the door is conceptually 'locked' and thus can't just be easily busted open. Last we left off we had just rolled to see if him leading us somewhere would result in us inadvertently coming to harm. It was a 50/50 because the location is probobly dangerous and the spirit doesn't really know what it was doing, and the roll results were... The last thing that happened before the session ended, we heard banging coming from the closet.
All of this came from a series of rolls on a bunch of collected random tables! Getting a sense for what those table results mean, having so many tables, and stringing them all together is not the easiest thing in the world if you aren't already experienced in roleplaying, but it is the purest improve experience I think you can have in a TTRPG outside of just roleplaying with no rules I guess! Please try it, I think you'll have a whole lot of dumb silly fun~
