Navagon: Looks like they've got some serious talent. I hope they're only planning on doing enough right now to get some investment into this project or this game won't see the light of day until this time next decade. They're going to need more people to maintain those kinds of standards.
Even so, if nothing else that looks like a good enough engine for them to be able to license it out and get in some money that way. Whatever the case, I hope they do what it takes to keep this thing alive.
Funny thing: all this graphics are made on 2 i5's and it is working on i7 with ease....
About the financing... they can easily put the game on Kickstarter or a simillar site.
But yet they first need something more than a trailer for sure.
