Actually, the Infinity devs are currently considering going the kickstarter route: they already have a few showoff vids, so they could definitely pull off some good advertising campaign. They have finally come to the conclusion that two guys simply can't make it in a decent time frame: the engine they've been developping over the past years is getting to a state where it is definitely usable to make the game itself, but they want to licence it first and be sure to have it really stable, mature, and if I'm not mistaken, quite portable. Which ofc takes as much time and effort as actually getting to the simply working point...
and yeah, finally they're probably going to let the community help financially (remember, back in the time, when the project started, there was no kickstarter, or at least it was not as well known as it has become these years). I still have faith in the project, though I've long stopped being a regular of its community.
