I think it's in a weird place. If the campaign had kicked off in January, at the height of the OGL fiasco, I think it would have hit Kickstarter like a tidal wave. But at this point, I think the people who have noped out on WotC or D&D as a result of the OGL have all largely done so.
I think this game is like 13th Age in that it is destined to be successful in the sense that it will be self-sustaining, there will be groups that love it and play it for years, and it will be a favorite among game designers and elements of it will show up in other games for the next 15 years. But it's not going to dethrone even Pathfinder 2, unfortunately.
