Love what this project is aiming for. I'm glad it's happening. It's also fun to observe framerate fetishism on Playtronic's forums where questions about support for 120+fps are popping all over the place. I tend to feel that people who aren't concerned about, say, gameplay, game length, quality of content overall but hedge their support on the framerate have their priorities in a very weird place. ;)
I'm super excited about all this, and if anybody can deliver a game, it's these people, but I can't think of a single Kickstarter that's listed an endless number of stretch goals (including cross-platform support, especially on Linux) and then delivered on them, let alone doing it on time.
