I'd say it's more like they turned off the game after the opening cut scene. This doesn't really qualify as a fumblebrag because they didn't actually start.

They assume that funding was in the bag already, that the product would get built on time (or at all) and that even 1 person would sign up. Maybe they would, maybe they wouldn't.

They were right about one thing though, the timing was fortunate that it was squashed just a little past the idea stage.
