H-I
- The track "Dark Interval" from Half-Life 2: Episode Two sounds remarkably similar to "Final Hours" from The Legend of Zelda: Majora's Mask (fittingly, it plays over the ending credits of Episode Two, which is the final moments of the entire Half-Life series for now).
- This isn't particularly surprising, as Half-Life 2's lead writer has stated that he was inspired by Majora's Mask when writing some of the atmosphere and characters of Half-Life 2.
- Halo Series:
- Halo is another franchise that plagiarises itself: In Halo 2, the Delta Halo Theme is a suspiciously similar version of the series' Theme Tune, and "Leonidas" is a soundalike of "On A Pale Horse" from Halo: Combat Evolved.

- Not only that, but pay attention to the tune that plays when Spat, the Big Bad, appears. Ring any bells? Well, let's just say it's one of the reasons a reviewer said Spat was practically a hamster version of Kefka from Final Fantasy VI.
- Hard Corps: Uprising has a few examples. The boss theme sounds similar to Endless Despair from BlazBlue: Continuum Shift.

- "Now Or Never" is a Self-Plagiarism of Danger's own "7:53" and "8:02" from Furi, The Game Bakers' previous game.
- The end credits theme, "Free Fall", sounds like a downtempo take on Haddaway's "What Is Love?".
- This track from Hebereke's Popoon for SNES sounds very similar to Two Unlimited's "Get Ready For This".

- It is readily apparent that the theme song that plays when you fight Ryth, a character from the Infinity Blade series that is fought as an Optional Boss in the second and third installments, is more than a bit similar to Duel of Fates, the most iconic song in Star Wars: The Phantom Menace. Considering the battle against him involves a duel with lightsabers by another name and he speaks with a voice that sounds somewhat like Darth Vader's, it's clear that this is intentional.
- Interstate '76 had a number of Suspiciously Similar versions on its soundtrack, mostly of '70s funk songs like the Ohio Players' "Fopp", The Isley Brothers' "That Lady" and Curtis Mayfield's "(Don't Worry) If There's a Hell Below, We're All Going to Go".

- Igniz, one of the cheapest bastards that'll you ever face, pulls this twice. His 2001 theme , Kare koso Saikyo (I'm the Strongest!), is a faster rock version of Original Zero's theme. In 2002: Unlimited Match, he's given a new theme called Save The Universe, which sounds like Mildred Avalon's theme from Arcana Heart.
