So firstly, full dusclosure: I ended up being a contributor to this project. However, I did not start that way. So take what I'm about to say with whatever size of grain of salt you want, I'm going to talk a bit about why I backed the game, decided to contribute to the game, and continue to support the game and it's community.
First, it's "Now". Arguably, we all game to deal with issues we want to see resolutions to, whether subconciously or not. By playing in a modern setting, with no (little) fantasy elements we are forced to call things what they are instead of hiding them behind anaologs. I prefer this gaming method, but then I'm more of an "in-your-face" kind of person.
Second, it's "Military" or at least clsoe to it. It doesn't become a simulation, which very few people would find entertaining, but at least incorporates the military accurately into the setting (this is the part I was involved in). Coming from a military background myself, I always feel slighted when an IP is created that references the military but does so with such a degree of inaccuraccy as to make it insulting.
Third, it's from Feral Games, and they are by far the most responsive publisher I have ever interacted with. With small publishers you tend to either get the people that are bending over backward to try and make everyone happy and end up with a product more limp than wet paper, or is so passionate about their product that they refuse to change even when legitimate concerns are voiced. Feral games find the middle ground, listening while also not giving in to every whim. And that's just it, I started as a backer and became a contributor (In the core book, an mission in their mission pack, and a side project), and you could do the same.
