- Ascended Fanon: At the beginning of the series, Pablo was just a normal (though often overpowered) character. When the programmers found out about his Memetic Badass status, they put a huge stained glass window of him in Backyard Skateboarding.
- Bad Export for You: Backyard Soccer: MLS Edition and Backyard Basketball 2004 were released in Europe, with all the pros removed.
- Cash Cow Franchise: This franchise was the cause of Humongous Entertainment making a profit. It seemed to evolve further into this as soon as Atari hijacked the series, but it later lost this status as the quality of the games went down and the series lost relevancy.
- Creator Backlash: Most of the former Humongous employees detest the later games in the series, if the Humongous Alumni page on Facebook is anything to go by. One of the former artists even responded to Evergreen's revival announcement with "This just made me throw up in my mouth a little. Nice to see them flogging that dead horse."
- Cross-Dressing Voices: Most boys are voiced by women.
- Executive Meddling: A positive example - after Backyard Baseball didn't perform well in its first year, everyone at Humongous was convinced not to make any more games, but Ron Gilbert pushed them forward. And surprise surprise, they ended up outselling their already popular Junior Adventures. It got worse when Atari took over, however.
- Franchise Zombie: The 2007 titles onward (Continuity Reboot and on) are pretty unanimously considered this, as they were all made following the bankruptcy and closure of the original Humongous Entertainment studios. This is the point where the series slowly devolved into a major sports league cash cow, with a pretty obvious lack of care for the quality of the games.
- Keep Circulating the Tapes: Evergreen, the current rights holder of the series, has gone on record stating a re-release of any of the older games is heavily unlikely due to rights issues with the pro players (this wouldn't affect the original Baseball and Soccer, however, since they didn't feature any pros to begin with). note This means the only way to play any of the old games at this point is to buy them secondhand or obtain them through... other means. However, in April 2019, the official Humongous Twitter tweeted this image of the original Junior Sports logo.
- Magnum Opus Dissonance: Humongous had no intention of this series outselling their Junior Adventures, especially since Backyard Baseball performed poorly in its first year.
- Mythology Gag: Pablo's Easter Egg (where if you hold shift and click on him, he reveals that he doesn't actually speak Spanish) is actually a nod to his voice actor; the development team was unable to find a suitable authentic Latino voice actor, so they simply took the auditioner who sounded closest to such. His only experience in Spanish-speaking was learning it in classes, as he was actually non-native. The dialogue was actually thrown in as a joke to poke fun at this; see this article for more information.
- The Other Darrin: The series has had many different voice casts. The voices that most people are familiar with, and what's considered the definitive voice cast of the series, are the 1997-2001 voices with Jen Taylor as Sunny Day. For Baseball 2003 and Soccer 2004, the recording moved to San Diego with the Audio Godz voices, including Lani Minella as most of the announcers alongside some other big names such as Ryan Drummond. 2003-2005 moved back to Seattle, but with a totally new cast (except Dex Manley), including Samantha Kelly as Sunny Day. 2006 onward brings back a few more of the classic voices, such as Mark Lund, Dolores Rogers and Shelley Reynolds. Chuck Downfield (Clem Daniels) and Barry Dejay (Dex Manley) were the only Seattle actors who were never replaced.
- Production Posse: A number of voice actors in the series are Sonic the Hedgehog veterans, due to it being recorded at Bill Corkery Productions, where the Sonic Adventure-era games were recorded. Notably, these include three versions of Tails (Corey and Conner Bringas and William Corkery), all of Chaotix (Bill and Emily Corkery and Marc Biagi), Lani Minella (Rouge), and even Sonic himself, Ryan Drummond.
- Additionally, many voice actors from the Super Mario Bros. series are regulars here, such as two separate versions of Princess Peach (Jen Taylor and Samantha Kelly, both of whom have also voiced Toad and Toadette), Dolores Rogers (Bowser Jr.), and Dex Manley (Lakitu prior to Mario Kart 7 and the announcer for Mario Golf).
- Talking to Herself: Lani Minella plays both announcers in Baseball 2003 and Soccer 2004.
- What Could Have Been:
- Basketball 's credits list the people who programmed an online mode, suggesting that it would have had online play. Football 2002 also has a screenshot in the help files that replaces "Network" with "On-line", suggesting it was supposed to be this instead of LAN.
- Peyton Manning was going to be one of the playable pros in Football 2002, but he was removed before the game was released.
- A network mode was planned as early as the very first game in the series. One of the pitches for the original game went into a little detail about this, and even mentioned a possibility of being able to spectate an in-progress network game. This idea was ultimately dropped for the final product likely due to the high development costs and complexity of adding such a mode that wasn't likely to be used very often, especially since one of the target audiences for these games was families who had budget computer setups.
- According to some data in the game files, a console port of Backyard Skateboarding was being planned during development.
- Write Who You Know: The Backyard Kids ran on this. Nearly all of them were based on kids the developers grew up knowing — in fact, the entire purpose of the game was that they were meant to represent the kind of kids that you would know in the neighborhood. To top it all off, many of the stories you can listen to from their player cards were actual stories from the staff themselves, or from people the staff knew.
