Those of you who have been following along in the documentary know about the design vs. money tension we've had on this project since the early days. Even though we received much more money from our Kickstarter than we, or anybody anticipated, that didn't stop me from getting excited and designing a game so big that it would need even more money.
I think I just have an idea in my head about how big an adventure game should be, so it's hard for me to design one that’s much smaller than Grim Fandango or Full Throttle. There's just a certain amount of scope needed to create a complex puzzle space and to develop a real story. At least with my brain, there is.
As a side note, it appears that a majority of the backers (or at least, those who identify themselves as backers online) are fine with expanding the scope of the game. And also, that those who complain the loudest against it do not appear to have put any money into the project (like parent poster).
