I think there are quite a few things discussed in the original kickstarter, and after, that have made it to the game indeed. Let´s not forget all that please.
Even in the video you like to quote as nothing like what we have today (where Braben discusses the way the galaxy would work out) there are clear and distinctive points in it that allude directly at how Powerplay works exactly for example (
min 3:01 or 4:55 in that video). You just chose to ignore them selectively.
I understand that you may have a personal vision of what the game should be and have chose to interpret Braben´s words in a very personal way, but what it is difficult to argue is that FDEV have delivered quite a lot of what they said they would. And that includes lots of elements in that Braben´s video aswell.
The fact you dont like it or want a different set of priorities is fine, but let´s at least give credit to where credit is due.
There is also the element of risk we take by going through a crowdfunding process. Name me a single kickstarter or crowdfunded project of the magnitude of Elite or larger that claims to have fulfilled all their promises and I ll show you a lie.
