* The infamous "Trials of the Magians" quests in ''VideoGame/FinalFantasyXI''are this. If you're making an elemental weapon the number of monsters killed per trial tend to number in the 100-300 range. For non-elemental weapons however could be looking at 700 kills for just a single trial.

* ''VideoGame/XenobladeChroniclesX'' has numerous missions where your team is requested to clear the indigens out of certain areas. The explanation is generally that the wild animals are interfering with resource-gathering or are hostile and powerful enough to kill field workers and need to be culled.

* ''VideoGame/TheLordOfTheRings:TheReturnOfTheKing'' tallies not only how many enemies you kill but if you properly execute the controls while doing it. It determines your mission rating. Luckily there's plenty of sites that list a manual cheat code to make all your mission ratings Perfect.

* In ''VideoGame/ChampionsOnline'', this pops up a couple times in Canada - you're given 3 separate missions requiring taking down 150 enemies of a given faction - Justiciar gives Terror Halt (150 Hunter-Patriots), and both [[{{SCTV}} Douglas McKenzie]] and Mark Derringer give missions to take out 150 Viper Agents (Snake Harmer and Make Snakes Moan).

* ''VideoGame/DarkCloud'' definitely qualifies. That seventh character slot in your party is for none other than Dran. The icing on the cake is that his playability won't be limited to the dungeon. He can be used on the map just like the main character. The catch? You have to slay 999 monsters...On every single solitary dungeon floor you've visited, including The Demon Shaft which by itself has 100 floors. Add to this that there are floors in which you must use one of the members of your party rather than the main character and that one of these characters [[TheLoad is Goro]] and you hit the motherload of FakeLongevity.

* In ''VideoGame/DarkCloud'' you have the option of gaining Dran as an ally. You can even use him on the main map above ground!...Provided you slay 999 monsters on every single floor of every single dungeon you've played through including the Demon Shaft (Which has 100 floors by itself). The only exception are the boss floors, but add in the fact that the game has floors where only certain characters can be used as well as the fact that one of those characters [[TheLoad is Goro]], and you have a task that is in the most humble of terms virtually impossible or just not worth it. There's also the fact that your weapons are breakable, you are prone to thirst and some of the floors take advantage of that fact by causing you to be thirsty.

* This and TwentyBearAsses are the most common mission types in ''{{Wizard 101}}''.

* ''VideoGame/LightningReturnsFinalFantasyXIII'' takes this to its logical extreme. Most Canvas of Souls quests require a set number of items to complete, most being VendorTrash dropped by monsters, however two quest givers require you kill an entire species, and [[UpToEleven one person asks that you]] [[KillEmAll kill every single monster in the world.]]

* ''Franchise/TheElderScrolls'' likes to do this from time to time.

* If you want to progress through the plot of ''AgarestSenki2'', you'll need to do this trope.

* ''The'' most common quest bar none in ''LaTale''. Annoyingly, quests to kill X Monster A always comes before the TwentyBearAsses quest for Monster A. That is, ''after'' you've sold the VendorTrash you're supposed to collect.

* TheHunter's sidequests in ''VideoGame/BrutalLegend''.

* Killing X amount of monsters with a specific technique in order to unlock certain skills or get achievements is as close as ''{{Vindictus}}'' gets to the trope -- the main quests mainly have you focusing on clearing dungeons and instances, which pretty much entails killing ''everything''.

This quest can be combined with TwentyBearAsses, either as part of the same quest or occurring in the same game. These are sometimes also called "{{Pokemon}} Missions": GottaCatchThemAll!

* ''VideoGame/XenobladeChroniclesX'' has numerous missions where your team is requested to clear the indigens out of certain areas.

In ''VideoGame/DarkCloud'' you have the option of gaining Dran as an ally. You can even use him on the main map above ground!...Provided you slay 999 monsters on every single floor of every single dungeon you've played through including the Demon Shaft (Which has 100 floors by itself).

There's also the fact that your weapons are breakable, you are prone to thirst and some of the floors take advantage of that fact by causing you to be thirsty.

* Although later content tends to move away from this, these still crop up in ''VideoGame/CityOfHeroes''. They're usually in older story arcs, and dressed as your character beating a lead out of them on the whereabouts of a certain villain or plot. Generally speaking, the improvement is that newer content now longer sends the character to defeat ten enemies far too strong for him in a distant zone far too dangerous for him. The classic example from the older game was being sent to defeat [[EvilSorceror Circle of Thorns]] enemies in the twisted and deadly Perez Park.

* The Ecology Quests in RomancingSaGa, you have to kill all the monsters that preys on the monster population you are trying to boost. (Kill birds to increase fish population, kill bugs to raise plant population, etc)

* In ''VideoGame/MassEffect1'', there's an overly long sidequest that involves you wiping out what pretty much amounts to a geth ''army''. While there is no specific number you have to kill, you have to wipe them out on five different worlds. This will take at least an hour, probably double that if you explore each planet looking for stuff.
