As I facilitate more roleplaying games, I find myself leaning more towards sandbox experiences with a large cast of NPCs. I establish a starting scenario to introduce these characters over the first few sessions without much of an idea of what the narrative is going to be. This is not to say that I do not plan any story - I often like to have something happening at the forefront in a session but it is determined by player and NPC actions instead of pulled from a plan. To do this I maintain session notes to remind myself of who interacted with who and how it went but this becomes painful when I need to trawl through notes from multiple sessions. Here is where I believe a tanglegram could benefit my and your campaigns.
A system for playing science fantasy adventures in the future of old is the tag line for Hypertellurians. It is an RPG that conveys its sword and planet themes well through its use of flavourful character powers that, alongside the advancement system, encourage heroic play. However, the cohesion of the subsystems does not achieve a smooth-running engine for producing the types of stories it aims to help tell.
Dread was the first roleplaying system that I used as a game master and I recently had the pleasure to be a player of it remotely. My friend wrote a scenario that was inspired by an SCP article and it was an excellent time for all involved - I even died horribly to some freaky monster and like all good monsters I cannot begin to even describe it properly. Traditionally a game of Dread uses a Jenga tower and has players pulling a block for a given action should their character be under duress or working out of their skill. This lends to a beautifully tense table that blends perfectly with the horror genre that Dread lends itself too, however using a Jenga tower remotely is uncomfortable.
In spite of Dungeons and Dragon 5E being the second system that I was a game master (GM) for it required a surprisingly amount of effort to try being a GM for a different system after DnD 5E. I chalk this up to DnD 5E requiring a deceptively great deal of energy to plan and run, a lack of experience likely also affected this, when compared to something like Dread which I had started with. In all likelihood I was under the impression that a new system would take more effort than just maintaining my tumultuous relationship with DnD 5E, however I wanted change and in a moment of clarity I purchased a copy of Blades in the Dark.
The use of random tables in my games are still predominantly focused on the before aspect of the game - the preparation. However, in my most recent campaign of Mutant: Year Zero I did return to utilising random tables during a session and I found that I very much liked the random aspects they can introduce while also allowing a modicum of control.
Plagued by dreams of mechanized humanoids descending into green cracks in the Earth is what originally inspired me to create the Lumbrik class for DnD 5e. I liked the idea of robotic or robotic adjacent heroes in a fantasy setting but I found the Warforged of Eberron to be a little mechanically bland - I suppose without the context of Eberron they just feel like any other race in DnD 5e to me. Due to the incessant violent coughs and ejection of blood from my throat caused by contact with Dungeons & Dragons - yes, I know I should have it looked at - I decided to port over my custom class to The Black Hack so that I could use it again.
I have found that the role of the Game Master is a challenging but rewarding one. It can be a stressful job which requires forethought preceding - and an agile mind during a game. However the joy of developing this skillset can be felt every time I play. The smiles, laughter, and expressions of disgust or horror on the faces of my friends are good - but I could not tell you if that outweighed the satisfaction and excitement I feel when I finish exploring a new roleplaying game.
The first time I read about level 0 funnel dungeons in Dungeon Crawl Classics (DCC) I was smitten. After years of playing in games where the backstory of a character was either non-existent, a re-telling of yet more murdered parents, or something of the sort I was ecstatic to try out the process of the funnel - just for something different at the very least.
