You know what, on second thought, an RPG like Darklands could probably go a LOT farther with the limited funds that Kickstarter could produce vs. a completely isometric RPG. I'd be really happy with that route too. Something incredibly old-school where the player's imagination factors into a large part of the appeal of the adventure.
A brilliant isometric RPG is what I'd like. Please don't waste funds on voice acting, that would take up a lot of money. Focus on a strong story and gameplay. Don't do it anytime soon, since we don't want any donator fatigue. And obviously ignore everyone saying 'Planescape'. That defeats the entire point of the Kickstarter.
