Plenty of bugs and missing features, the game is labelled as complete but isn't.
Wait another year at least for the game to actually (maybe) be at least feature-complete, if not bug-free.
A boring, cliche story about annoying children with little gameplay and easy puzzles. There's really not much to say besides the fact that the "game" is just bad.
Even after updates the game mechanics are still not the same as the original - like formations mattering or ballistics. Your money would be better spent getting Emergence (Cataclysm).
