reviews of free multiplayer games
My anitvirus picked this one up, wouldn't recommend...
Are you sure it isn't just because it has access to your internet socket ports?
A nice game and a LAN server is easy to set up although single player is good too. Also has a large community with a dev who regularly goes through the forums to help and some YouTube channels streaming it.However has a large learning curve if you haven't played a civ game before.
