If we use the Pi Tweets as a precedent, those were 28 consecutive tweets leading directly into the Swan Song live show. So, I still stand that July is too far away. But I doubt it will be the same number of days.
From the tweets, we have a modern naming method, and modern terminology associated with modern weaponry, all of which imply this does not have to do with Blades.
It sounds too serious to be Nebula Jazz or Swan Song, but could be in the same universe.
Honestly, the game system that keeps running into my mind, is Shadowrun.
Because what the tweets are implying is a small group who are supposed to be doing an in and out job to steal a blade, with one lunar cycle to do it(which is a fancy way of saying 29-30 days; also reeks of magic ritualism since almost nobody uses that phrasing), and they ran into a problem named Johnny G, and are trying to escape under fire.
The reason I don't think it's Shadowrun is because we've already done. Could be doing a later edition. But I feel like it's a different system.
I aslo feel like it's a one shot rather than a new show because JP kinda has a full plate with normally three of his streaming days being reserved to instead stream the Rollplay shows for four hours a day.
Great for the Rollplay community, probably "eh" for those who sub to his channel so they can watch him yell at Kelly for wanting to check his e-mail.
So unless JP feels comfortable doing back to back a lot, I don't think it's going to happen. Not without cutting one of the other shows. But who knows, could be wrong.
Could it be that Corialis system that's been a top 5 seller on Drive Thru RPG for like the past month or two?
