Not because multiplayer is 'much cheaper' to make but because the devs designed and developed the games you mentioned with multiplayer in mind, since from the start. Second, TOR (The Old Republic ?) and Anthem are both games developed with multiplayer in mind, that's why we may see multiplayer properly done in both these games. Leaving modders to do the 'dirty work' is a practice Bethesda does and we all condemn here. Even if the developers intend to release a multiplayer mode/patch/DLC after the initial game release (see Klei's Don't Starve Together), then they should properly do that, not modders. First, I don't believe developing multiplayer modes should be left to modders. I am referring to the fact that modders are doing a multiplayer mod for a game which, at first, doesn't need it.
