Doom Eternal from id Software sold 3.0M digital units in March, more than three times what Doom sold (957K) during its launch in May 2016. The latest entry in the seminal franchise benefited from strong reviews and the positive reception of its predecessor. However, as a primarily single-player game, Doom Eternal will likely have a shorter revenue tail than other multiplayer shooters that monetize through the regular sale of in-game content.
