People paid for PP? Do you really thing if people knew what PP would become when they were pledging money they would have been happy with it?
Yes we paid for PP, just as we paid for the Stellar Forge, shaders, Diamondbacks, Asps, multi-cannons and so on. We paid for the game to be developed, for a concept to be fleshed out. It is being fleshed out and developed as we argue here and will continue to be so thanks to the efforts Frontier is also putting into keeping the cash-flow going.
If you pay to get the game YOU want developed, you are bound to become disappointed. But if you pay to let the game developer realise their dream, you are much less likely to be disappointed. But you need to let them have their artistic freedom to do so. Warts and all, ED is still being developed and is blooming before our eyes.
If backers want their money back because things don't quite turn out exactly how they wanted it, they do not understand the concept of backing. It saddens me to see this happen in the ED community (again), and I hope it is mainly the loudmouths here on the forum that have that view on things. The rest, hopefully, are happy to truck along and see where things go.
