I'm so playing it! I remember I saw a trailer back in May and I'm like, damn, I have to wait that long? Then I totally forgot about that game until you brought it back up. I'm a big fan of RTS games, like Age of Empire, Age of Mythology, Starcraft, etc.
yes its free you can play mostly everything, if you are not into achievements and stuff, you can get the full experience, i think is even better than the first one, I like the fact that you have to do missions to level up, and even better you can do most of the missions co-op.
