Anti-Idle is a game that loves references, especially to 2000s culture.
- The Arc Number is 9001, a reference to the "IT'S OVER 9000!!!" meme. It shows up in several places, such as the old level cap (before it was raised to 9002) and your max HP for certain missions.
- An achievement for printing several millions of Coins is called 'This is illegal, you know', a line taken from The Legend Of Zelda C Di Games.
- Grinning Colossus comes from the game You Have to Burn the Rope. You even have to use a burning rope to kill him, too!
- The 'potion [PROFANITY] 1/5' skill is a reference to the MARDEK series.
- Many Battle Arena monsters, especially ones in earlier zones, look like monsters in MapleStory.
- Pokayman City is a reference to Pokémon. A 2016 update even added what are clearly Pokestops.
- The Corruption is based off Terraria.
- Secret Dungeon area is inspired by Dungeons & Dragons.
- Worst Moon difficulty in the Battle Arena is a reference to the Bad Moon difficulty in Kingdom of Loathing.
- The Dragon of Wisdom is based on the Tree of Wisdom from Plants vs. Zombies.
- One of the TukkunFCG cards is a Big Daddy.
- "lrn2craft" chain of crafted melee weapons is a long list of polearms taken straight from a strip
of The Order of the Stick (which is itself a reference to Monty Python's Flying Circus). It also includes a broken greatsword with a green hilt, just like Roy's sword in the strip. - The Button Machine lets you hire Grandpas to click the button for you, or as the game puts it, "A nice grandpa to click some buttons!" Don't worry, they don't turn into cosmic Humanoid Abominations like they do in the game they reference.
- One of the death quotes in the Stadium's Death Match is "All Your Name Are Belong To Us", referencing the extremely poor translation.
- In the old version of Mute Mute Revolution, and MMR X: Special Edition, one of the "songs" has notes that are set to the rhythm of Rick Astley's "Never Gonna Give You Up". In other words, you get Rickrolled by the chart.
