You get the 3 part installer. It does install the game to the PC. Game launches. Local play on a PC is just fine. But network play against friends isn't possible - nothing but network errors/not logged in messages. Zero help in the game itself, nor on the manufacturers website in their info. Turns out, the game as installed does NOT come with the needed network matchmaking infrastructure. As others have pointed out, to do network connections to play between computers, you still need to install and run a needed network account matchmaking application: GoG's Galaxy in this case. And the Game, nor the game description in GOG, tell you any of this.. so you are frustrated with a half broken game until you happen to come across this information in the reviews as you go to add yet another bad review for this game. Seriously? Its not that there needs to be a matchmaking service to make cross internet play doable.. .I get that. But deliver that, or at least the instructions that its needed WITH THE GAME. Sheesh.
