Well Quake, is one of the most influential shooters in a long line of influential shooters. Id's magnum opus was their final step as they brought the FPS into full 3D only to stagnate until Wolfenstein: The New Order came out. As for the game itself, it's pretty damn good. The level design (most of the time) is really good. The enemy balancing is just bad, however. It's at its worst when they throw ones in that both hit like a truck and can shoot the flea of a dog. Also, they like to drop melee goons right behind you which would incentivize checking your back occasionally but my brain likes to block out traumatic experiences. Also, the enemies seem a little too bullet-spongy maybe it's because ammo is so plentiful but I feel like the only two weapons in the game that dealt significant damage were the super nail gun and the electricity gun. Both of these are the quickest ammo drainers. I played on medium so I have no idea what hell awaits me on hard. Quake is a good experience just didn't exactly age well in the right places.
