Also, I really feel Galaxy Defenders is vastly underranked, but I hope time (and maybe Operation Strikeback & Extinction Protocol) will work wonders for it.
I suspect time is going to be what does the trick. GD feels to me like one of those games that started off under a lot of people's radar, but is likely to grow into something that's more enduring. As time goes by, it gets recommended in more and more places (I see this all the time in "recommend me a good co-op game" threads), and more and more players will play it, review it, and so forth. I would not be surprised if it becomes like War of the Ring (which is practically a de facto recommendation whenever anyone goes looking for a slightly-heavier two player game on BGG, it seems like) except for soloable co-ops.
The farther we get from the Kickstarters the better, as well. The angst over missing out on minor extras has done nothing but hamper the game's growth.
