This is an officially licensed TTRPG set in the GItS: Arise universe. The kickstarter just ended so I’m not trying to convince anyone to back it, I just think it’s impressive that they only wanted ~$11k to fund the project and raised almost $500k. That’s awesome!
Blades in the Dark, it’s called.
The setting is quite different from Dishonoured, though you can see the influence clearly and it’s mentioned by name as a media touchstone.
