Video game knock-Offs have existed almost as long as video games themselves. Whenever a title becomes wildly successful, other developers inevitably try to capture some of that magic. Sometimes the inspiration is subtle. Other times it’s so obvious that players can identify the source material within seconds.
To be fair, not every game on this list was a bad game. Some eventually found their own identity and developed loyal fanbases. Still, it’s hard to ignore just how closely they resembled the hits that inspired them. These are ten video game knock-offs that looked a little too familiar.
1. Yoyo’s Puzzle Park (Copying Puzzle Bobble)

The success of Puzzle Bobble inspired countless puzzle games throughout the 1990s. Yoyo’s Puzzle Park followed the same colorful bubble matching formula, helping it earn a place among the era’s lesser known video game knock-offs.
2. Limbo Of The Lost (Copying Multiple Games)

Unlike most entries on this list, Limbo of the Lost wasn’t linked to just one source. Investigations revealed assets that appeared to have been taken from Oblivion, Diablo II, Thief, Unreal Tournament 2004, and several other titles, creating one of the strangest plagiarism scandals gaming has ever seen.
3. Genshin Impact (Copying The Legend Of Zelda: Breath Of The Wild)

When Genshin Impact was first revealed, comparisons to Breath of the Wild dominated gaming discussions. The cel shaded visuals, climbing mechanics, gliding system, and environmental design looked so similar that many players initially dismissed it as one of countless video game knock-offs chasing Nintendo’s success.
4. Bayou Billy (Copying Double Dragon)

Like many games released after the success of Double Dragon, Bayou Billy centered around side scrolling brawling and street combat. While it added driving and shooting segments, its roots in the beat ’em up craze were easy to spot.
5. Freedom Planet (Copying Sonic The Hedgehog)

At first glance, Freedom Planet looked like a love letter to Sega’s mascot. Fast movement, looping levels, animal heroes, and momentum based platforming made comparisons to Sonic the Hedgehog unavoidable.
6. Saints Row (Copying Grand Theft Auto)

The original Saints Row arrived when players were hungry for another open world crime game. Many immediately viewed it as one of the more ambitious video game knock-offs, thanks to its gang warfare, vehicle theft, criminal storyline, and obvious similarities to Grand Theft Auto.

7. The Simpsons Road Rage (Copying Crazy Taxi)

Few gaming lawsuits were as straightforward as this one. The Simpsons Road Rage borrowed the core gameplay loop of Crazy Taxi, asking players to pick up passengers and race through a city before time expired. Sega eventually sued over the similarities.
8. One Of The Most Famous Video Game Knock-Offs Was Wacky Wheels (Copying Super Mario Kart)

After Super Mario Kart became a massive success, developers rushed to create their own mascot racers. Wacky Wheels adopted colorful animal drivers, item attacks, and kart based competition that looked remarkably similar to Nintendo’s formula.
9. Fighter’s History (Copying Street Fighter II)

Released during the fighting game boom of the early 1990s, Fighter’s History borrowed heavily from Street Fighter II. Similar character archetypes, special moves, and visual designs even led Capcom to take legal action, making it one of the most famous clone controversies in arcade history.
10. The Great Giana Sisters (Copying Super Mario Bros.)

When players first saw The Great Giana Sisters in 1987, many immediately noticed how closely it resembled Nintendo’s Super Mario Bros.. The side scrolling platforming, enemy placement, hidden blocks, and overall level structure helped make it one of the earliest video game knock-offs to attract widespread attention.
The gaming industry has always borrowed ideas from successful titles. Sometimes that inspiration leads to innovation. Other times it creates games that feel a little too familiar. The line between homage and imitation has never been completely clear.
