Hmm...I've never been a big fan of CCGs - I mean, I did and still do collect Pokemon cards, but I never got heavily into the battling and trading thing.
That said, this looks like an interesting take on the genre. I do so love 4X and RTS games, and injecting that sort of cerebral, strategic mindset into a game is, in my opinion, a good thing as long as it's done well.
I'll be keeping my eye on this and I'll see if I can get into the closed alpha. At the very least, Notch was right when he said people would be annoyed because it's not Minecraft.
