Hi, me again...
After seeing some very heated arguments pop up on various sites about what a game should be to be a true old-school RPG, I'm convinced that unlike Double Fine have been you should be *very clear* about the scope and goals of the game that is going to be made, so you don't get the sort of long term resentment and grief that Notch gets from some Minecraft "fans". I.e have this on the Kickstarter page:
Related to that, with my earlier suggestion that you do like Order of the Stick and add milestone rewards to increase pledges, be careful that you don't alienate early donators. For instance, if you add iPad/console as a new reward if we would double the initial amount, I'm sure non-PC owners would (rightly) be overjoyed, and while I wouldn't begrudge them having the game there too, I'm sure you know you would face a level 10 inferno worth of people going "OH GOD NOOO! They are going to dumb down the interface!!". Because on the internet, believing something makes it true, no matter how much evidence to the contrary is produced.
Also, for goodness sake don't overcommit and burn out on this Kickstarter. Create something small(ish), original and most of all polished! Then do another one if it is successful. Best suggestion so far in this thread in my opinion has been from ex-Obsidian "tevans":
With all that said, I think something with the graphics level and gameplay complexity of Age of Decadence would make me very satisfied.
Final comment: If isometric turn based would become a "thing" with you but Kickstarter is too limited, consider talking to Fredrik Wester of Paradox. They are growing as publishing company and have shown they are willing to fund some out there stuff. I'm sure they would be delighted to have a famous team like you as a feather in their hat.
