Quake (video game)/YMMV

Crowning Music of Awesome: Trent Reznor.
Demonic Spiders:
- Spawns. They're fast, they bounce all over the place making them incredibly hard to hit, hit you for visible chunks of damage, and being blue blobs who don't move when they immediately see you, preferring to wait a second, it's easy to miss them in the dark until they're all over you. On top of that, they explode like a rocket upon death, meaning it's easy to maim yourself (or worse) if you're careless while killing them when they're in your face.
- Fiends. They're less mobile than Spawns, but in exchange, they're much more resilient, taking three rockets to kill, their leap attack hits very hard, and they're very keen on cornering you in a place where they can cut your ass to shreds with their claws. To make it worse, they almost don't flinch.
Game Breaker: It's debatable, but the Rocket Launcher was far and away more powerful than anything else in the game. The Lightning Gun, which was the last gun to be found and the one with the highest position, was only a true Wave Motion Gun when amped up with Quad Damage.
Goddamned Bats:
- Goddamned Scrags.
Just Here for Godzilla: The Multiplayer was far and away the main draw of this game (to the point of being the entire purpose of QuakeWorld), and id didn't make a predominantly single player game again until Doom 3.
Porting Disaster:
- The N64 port. Many of the best levels were removed or simplified, and the multiplayer mode is limited to two players only.
- Averted with the Sega Saturn port; it doesn't even use the original Quake engine, but Lobotomy Software's in-house Slavedriver engine, specially tailored to the Saturn. Despite this, it's a lot closer to the PC original.
Seinfeld Is Unfunny: This game codified a lot of tropes associated with modern FPS', such as weapon jumping/climbing, Capture the Flag, 1v1 arena, dedicated servers, lag compensation, green/brown palette, etc. However, it rarely gets mentioned in many Best Game Ever lists along with its progeny. Quake III Arena "steal" most of these honours instead.
That One Boss:
- Shamblers.
- The final boss is quite difficult as well.
That One Level
- The Pain Maze.
- The final boss level is quite difficult as well.
You Fail Geology Forever: Lava (even when molten) is thick, viscous and opaque, not the "fiery water" it is in this game (e.g. in the "Ziggurat Vertigo" level).
