Doom, alongside its sequel, Doom Eternal, is hands-down one of the best single-player FPS games to come out in recent memory. It and Titanfall 2 proved last-gen that shooters don’t always need to be entirely focused on multiplayer and that there’s a market for just the story and gameplay experience that doesn’t need to involve other people.
You’d be forgiven if you forgot that, at least in the case of Doom, there was a multiplayer mode as well. It had a few game modes and experimented with a Demon Rune that allowed players to transform into a demon, which likely formed the basis of Doom Eternal’s multiplayer.
But at the end of the day, it’s not what the fans are buying Doom for, nor is it what they are staying for. At least in the case of Doom (2016) further adding to the game’s single-player features probably would have been the better call.
Doom Eternal mixed things up a bit with its multiplayer and the dev team was still able to deliver it successfully alongside significant additions to the single-player through the addition of story DLC, Master Levels, and other neat features such as free cosmetics and other unlocks.
At the end of the day, though, while Doom’s multiplayer is fine, and there are plenty of people who love it, it would take a lot to ever shift the public perception and get people thinking that Doom is a multiplayer game.
