Looks like the developers of Defense Grid (Excellent Tower Defense Game) are looking for help to fund the next version. There are lots of levels of funding, lowest is $15 which gets you all the current Defense Grid content (original game and DLC) as well as whatever they manage to build on the way to and including the full DG2 if they reach full funding).
I'm in, this was my favorite Tower Defense Game.
