I just wanted to also point out that Pathfinder Online already had full funding before the Kickstarter, the goal was to make enough money to cut down on development time not to fun the game itself. Even then they only just got to their goal and that was in large part due to a lot of neat offerings for the Pen & Paper game and the loyalty of Paizo's community. The deal ended up including a big super dungeon for the roleplaying game, miniatures, PDFs of game books and some other swag. They also had already run another Kickstarter for a 'tech demo' that was funded in June last year.
Don't get me wrong, I think that an eventual Kickstarter for a City of Heroes successor project would be a great idea and I'd happily back it. But the situation is quite different from the situation with Pathfinder Online at the moment.
