Epic Online Services is mandatory if you have bought Ogre Kingdoms and want it to be recognised by the game, or if you want to play multiplayer. As someone who has blocked EOS on my computer, this means I am unable to play Ogre Kingdoms. EOS should be optional if you do not care about crossplay or multiplayer.
