The great thing about the original Doom is that when you start it feels just like a dumb shooter, but then you literally have to learn tricks and skills (like various strafing tricks, running in circle while shooting, position the enemies to shoot each other, etc) to actually defeat the enemies, especially as your ammo gets depleted. The skills are not explained or encouraged anywhere in the game, you just gradually figure those out on your own.
