* CashCowFranchise: The first game holds the virtue of being among the original 17 "Sega All-Stars" games for the ill-fated Sega Dreamcast, and the second appeared on the [=PS2=]'s "Greatest Hits" list for a time.
* ChannelHop: Creator/MidwayGames published the first two games, but ''Ready 2 Rumble: Revolution'' was published by Creator/{{Atari}} due to Midway's collapse. Creator/WarnerBros (current owner of the Midway properties) still controls the first two titles and their characters.
* DoingItForTheArt: WordOfGod said that Michael Jackson refused to be paid for his involvement in the game, content with just being a part of the game instead.
* FranchiseKiller: After ''Ready 2 Rumble: Revolution'' got [[{{Sequelitis}} canned]][[labelnote:note]]The game was developed by Creator/{{Atari}} though.[[/labelnote]] and Midway closed their doors in 2010, the hope for a new ''Ready 2 Rumble'' game is just about lost.
* HilariousInHindsight: In ''Round 2'', Shaquille O'Neal's alternate trunks are black, with white and red trim, the colors of Miami Heat... On which Shaq would play four years after the game.
* KeepCirculatingTheTapes: Physical copies of the first two games have gone rare. Even with the massive increase of interest after Michael Jackson's death, physical copies (especially the Dreamcast ports) are hard to come by.
** That said, it's trivially easy to simply burn a CD-R with an ISO of the game to run on a Dreamcast, so it's not as bad as you'd think.
* PromotedFanboy: Music/MichaelJackson, having been a fan of the original game.
* ScrewedByTheLawyers: In a similar vein to his guest appearance on ''WesternAnimation/TheSimpsons'', contractual issues prevented Midway from properly crediting Michael Jackson as a voice actor.
** Also, thanks to potential licensing issues between MJ, Shaquille O'Neal & the Clintons, WB Games (the current owner of nearly all Midway properties, including ''Franchise/MortalKombat'') is unlikely to put out an UpdatedRerelease of ''Round 2'' for a long time.
* TheOtherDarrin: Averted. Despite numerous reports, [[WordOfGod the head director of the game]] confirmed that all of the dialogue Music/MichaelJackson's character used was not recorded by a soundalike, but MJ himself. Though some say he's using his real, low-key voice while others state that it was pitched down afterwards to make him sound more masculine/tough.
* WhatCouldHaveBeen: ''Round 2'' was slated to get an Platform/{{Xbox}} port, but never made it past a [[https://www.youtube.com/watch?v=nTv7sIIVt1g proof-of-concept tech demo]].
