As a developer myself I'd highly recommend running away from this kickstarter as the video doesn't show any models, no in game scenes, no UI designs and basically I couldn't find anything started aside from the video & a quick map graphic.
The story is interesting and seems pretty fleshed out, plus I imagine you can't get much further than the previz stage on a project of this scope when funding out-of-pocket.
Only signed up at the $20 level, but may increase for other rewards if they provide more details in the updates.
Take a look at the Creative Team and check out their pedigree. In my opinion, it looks like they might just have the talent they need to get this thing off the ground.
