While Doom let me have fun from the beginning, Quake took some warming up to. Doom starts you off gently with low numbers of weak enemies, but the basic enemies in Quake can tear you to shreds and require concentrated fire. Trying to play in a slow, methodical way will get you killed, even when you feel like you're not making any mistakes. Enemies seem to come from random corners, grenades are bouncing everywhere, and the levels are so complex that it can feel random and overwhelming. The key thing to realize is that while sprinting around enemies in Doom was a careless way to play, it's what you have to do just to survive in Quake. The basic enemies using powerful but slow grenades was meant to inform you that the best way to handle an enemy is to be in constant motion and maintain fire as you pass. Once you get the hang of the combat’s momentum, this game really gets amazing. The high speed mixed with enemies that demand careful reaction placed within intricate levels makes for an experience that simultaneously rewards instinctive skill and observational intelligence. As much as it’s become a video game boomer meme to say, I have to admit that Quake really does hold up beautifully.
