Although Petersen said "Doom" was "nothing more than the computer equivalent of Whack-A-Mole", "Doom" received critical acclaim and was widely praised in the gaming press, broadly considered to be one of the most important and influential titles in gaming history. Upon release, "GamesMaster" gave it a 90% rating. "Dragon" gave it five stars, praising the improvements over "Wolfenstein 3D", the "fast-moving arcade shoot 'em up" gameplay, and network play. "Computer and Video Games" gave the game a 93% rating, praising its atmosphere and stating that "the level of texture-mapped detail and the sense of scale is awe inspiring", but criticized the occasionally repetitive gameplay and considered the violence excessive. A common criticism of "Doom" was that it was not a true 3D game, since the game engine did not allow corridors and rooms to be stacked on top of one another (room-over-room), and instead relied on graphical trickery to make it appear that the player character and enemies were moving along differing elevations.
