Our game right now is just a normal Masks game, but after the first Spiderverse movie a friend and I collaborated on a multi-table convention oneshot where each table was its own universe.
It should be noted that a lot of the ordinary Masks setup relationships will take a back door to the plot and events, as with a oneshot in general and even moreso with switching tables/universes things like Influence and relationships will take a bit of a back door to the action itself.
Masks - I currently did a session zero for this game this weekend, and will be doing the first session next tuesday. I've played Masks a bunch before, and having seen Across the Spiderverse twice recently I'm really looking forward to it.
Pathfinder 2e - currently playing through Abomination Vaults on my Sunday livestreamed variety game group. I think one player isn't enjoying it so much as he enjoys playing unusual characters more than the tactical combat itself, but I think everyone else is enjoying it.
SWN Revised: After two previous SWN campaigns, this one is a bit different. Instead of starting off as a free crew with a ship, the PCs are a part of a faction that's half mercenary company half adventurer's guild, that focuses on mech combat. So I made some systems for them to work their way up the ranks of the faction, a variation of the faction turn that represents different crews within their faction vying for control and influence, and a reputation system that unlocks more purchase options over time as missions are complete.
I made a few myself for convention oneshots that work well. They each consist of an evocative intro paragraph and several leading questions, and sometimes a neat picture.
I'm adding a section about them to Chasing Adventure, and wrote a new one that I'll be using for Dungeon World Day.
You found it! After centuries of rumors and myths, you are the first to lay eyes on the legendary Cloud Fortress. Despite the ancient battle scars covering its surface, the fortress's hull gleams brightly in the sun, its cloak of clouds falling away at your approach. As your hot air balloon softly touches down at the fortress entrance, its edifices begin to pulse with an ominous light.
-What mysterious technology seems to power the fortress (fans, rockets, crystals, etc)?
-What ancient battle did the fortress participate in?
-What terrible foe is it said damaged the fortress long ago?
-What unenviable fate do legends say befell the fortress's inhabitants?
-What powerful weapon did the fortress once make use of?
The important thing for these versions is that the table takes a 5-10 minute break to let the GM prep after character creation and questions being answered.
I hadn't thought of github as I'm used to considering it for code. I won't easily have time to copy it over again, but if someone else creates a copy on Github I'm happy to also link it here and from the google doc itself.
