The game itself is great, and the Fallen God expansion adds a very interesting faction to the game. You should buy it, just not on GOG. Currently the GOG version is far behind the steam version, and you are unable to play with all the factions because of it. If you play Fallen God you cant play with the earlier expansions Factions, and vice versa. Buy it on steam if the game looks interesting to you. Or try the versus Edition for free on steam. It has the base races and gives a good glimpse of what the game is.
