To add to tolknaz, I think your dual objectives of immersive design detail and actual "Role-playing" are intractably at odds and that is confusing us. The distaste for tactical combat is a very unusual dislike for someone who proclaims such a long history with RPGs and we could have an entire argument over that PnP-wise, but that's for RPG.net on another day. I acknowledge your preference and recognize the PnP game style; I've seen it before.
My problem is that you've already acknowledged the expense of full voice, but still proclaim the greatness of it without really acknowledging the inherent limitations.
If full voice acting is really *that* important to you, then I can say with pretty good certainty that absolutely no RPG will be available to you for a budget less than, oh say, $12 million US (You know what? don't even let me quote a number. Even that may be low). The cost of paying talented designers and engineers plus all the ancillary stuff to make VA worthwhile is an order of magnitude greater than what we're working with here. Quality of the actors isn't nearly as big a concern as the production required to make it happen. This kickstarter stuff just isn't your world.
