Did you see your name in "Backer list" in Credit?

I saw mine, in fact it was the very first one to pop up which I thought was awesome but also kinda weird. Though I think it may (and I am not a hundred percent sure of this) have to do with the fact that prior to beating the game I had managed to successfully enter in my Backer ID on my save file (when you are about to select your save file you should notice on the bottom screen it says "Select & Begin", "Option", "Title Screen" and if you've beaten the game "New Game +" along with their corresponding button. If you select "Option" at the very bottom of the menu it will say "Backer ID" select it and you can then enter your Backer ID which is located in both the title and within the email itself that FanGamer sent out saying your shipment/download codes are available/on the way.) so you might want to give it a try. Also while I'm thinking about it on the PS4 version of the game holding either Triangle or Circlespeeds up the credits while holding Square slows them down, and holding X "stops" them.

seiya   uh ok, well then I must be extremely lucky cause the few times I popped into the credits my name & the clan I chose has always shown up first under the Backer section . Also no problem and have you checked your backer survey? Cause you can still view what your survey responses were.

Well, 65k backers? Long credit roll?

It's a long credit roll, but you can speed it up or slow it down using the controller buttons and not every backer is listed just the ones who backed at the $100 + tiers since that was a backer reward for backing at those tiers which accounts for approximately 21,000 people or roughly a third (1/3) of all backers.
