I donated $100. Tim Schafer worked on the games that were a part of my childhood/adolescence, and I wanted to thank him by helping him create another game of a similar style.
I know I have no idea what the game is, but I do know this: He doesn't need a Kickstarter campaign to come out with a typical Double Fine game -- he needs it to come out with the kind of game no publisher would take on today.
And what kind of game is that? A classic point-and-click graphic adventure like those from the Golden Era. Therefore, we have every reason to believe he's going to deliver EXACTLY what we want. Don't you think?
And if there's one developer out there capable of making that kind of game today, it's good ol' Tim
