As I see it, the FPS always was part of the original promise (https://www.kickstarter.com/projects/cig/star-citizen/descri...) and I think it will be good.
To be honest, I'm tired of space games like Eve or Elite:Dangerous where you basically play as the ship.
From the beginning I had hoped, that it would be possible to EVA and fight onboard of a ship - and what was a little hope turned into a solid part of the game.
Do I think my money is wasted because there is nothing to play yet? No, not at all. The goal of crowdfunding is to give the developers the time and money they need and safe them from cutting corners.
Elite, for example. Its great flying, but there is no story and nothing to do besides grinding for the next ship. They rushed the game out of the door and its "nice", nothing more.
Even if everything fails, even if SC is crap or vaporware, I won't be disappointed. Roberts and the others tried and, to be honest, if they pull it off, they might give the industry the kick it needs to get back from yearly updates to FIFA, Battlefield or CoD.
Oh, and BTW: Nobody complains when Blizzard runs late with their games :)
