Bethesda will patch the new DOOM re-releases to make the mandatory login optional
After DOOM, DOOM II, and DOOM 3 all released on modern-day platforms, to the excitement of many, players were shocked to realize that they were forced to use a BethesdaNet account in order to actually play the games. This decision was met with a sizeable amount of backlash, with lots of fans criticizing Bethesda for adding online DRM to a 25-year-old classic game. After the minor controversy, Bethesda is walking back the decision, and is looking into patching all three games to make the login optional, saying it was initially included so that Slayer's Club users could earn points for their account, by playing the games. A fix should be out soon, though if you're really determined to play it without making an account, there's already a workaround on certain platforms.
