They finally added Solo play as a stretch goal!
STRETCH GOAL 30: SOLO MODE – LOCKED
If we reach this goal, acclaimed solo roleplaying game designers Shawn Tomkin (Ironsworn) and Matt Click (The Mecha Hack) will collaborate with The One Ring designer Francesco Nepitello in creating a robust framework to allow solo play. This will be released to backers as a PDF some time after the main fulfilment of the campaign.
