They had an incredible pmf - they could sell virtual spaceships in a game that didn't exist! People were hurling money at what they thought the product was going to be. It's just a question of how well they actually delivered on that promise.
That's not an example of product market fit, as the actual product: the game, never existed. The "product" in this case is a dream. "Star Citizen" means something very different to pretty much anyone who has thrown money at them.
My comment was referring to Improbable, not Star Citizen. I'd agree that SC seems to have reasonable product-market fit, but Improbable clearly doesn't if the parent comment is to be believed.
