The answer is simple. The story was done by two people, for 4 years, for free. This is what we could do on our own. But it's still not a complete game in its current form. It needs the graphics, the music and the combat system. For that, we have to pay a good couple of people for 18 months. Plus various licences, equipment, tax and ofc the rewards.
Don't think of the story as it was the story of a hack and slash RPG. This is a highly detailed world you can hardly find these days, in the spirit of good old times.
That's fair enough, but as I said above, think of it as a business undertaking.
Why should gamers donate to your project? What kind of guaranteed return can gamers expect from their investment? What have you done to establish the kind of reputation that would attract this kind of investment?
Tim Schafer's Kickstarter project took off solely on the basis of the fact that it's well...Tim Schafer. Everyone knows him and Double Fine. He's got a big reputation to put at stake in this project, and he knows that if he fails to make good on his promise, he'll probably never be able to show his face again.
Who the hell are you? And I don't mean that in a spiteful way. I just want to ask what claim you have to the confidence and trust of the wider community. You have much less of an established reputation. Just looking through the developer list, the only one that has any noteworthy background is Zoltan Gonda, whose last major project was the mundane Codename Panzers: Cold War (which I picked up for 3 euros new less than a year after release and I still wanted my money back), and apart from that the fairly respectable but not astonishingly great Haegemonia.
I see little in your project work to date to really convince me. The dialogue seems competent but very fan-ficish, and the fact that you have relied on forum members to proofread it for a project worth six figures sounds a little odd to me.
I think it's great that you have a vision for an epic and imaginative RPG world, I really do, but I see little to convince me that you can weave this into a coherent and high quality game.
Again, please don't think I'm being spiteful, but I do feel the need to say things as they are.
