Hi there streamlap, thank you for your interest and I apologise for taking such a long time to respond (for some reason I missed the notification that you had left a comment!)
Do you mean 'Dungeon World'? That is a Powered by the Apocalypse (PBTA) style game, which is slightly different to a game based on D&D mechanics, like FORGE. PBTA games tend to lean more heavily into the fiction, and often run best with multiple players working together to interpret the emerging story. Personally, I find FORGE easier to play as a solo game than PBTA, as I benefit from the increased mechanical crunch as a scaffold to hang my story from. If you prefer a PBTA style game, I can recommend Ironsworn as an alternative to DW, as that is designed to be played solo.
