As the saying goes, "Surprise! Nothing is absolute," and the gaming industry is no exception. Even the most iconic mega-IPs, which once transcended the hobby to become household names, are not immune to decline. Usually, once an IP reaches the stratosphere, it might experience fluctuations, but rarely does it hit rock bottom. Especially for long-running series with solid foundations, they typically have the stamina to shrug off a blunder or two.

However, occasionally, a developer's stubbornness or a publisher's sheer incompetence can send a top-tier IP into a tailspin. Years later, new gamers might not even be aware of the title's existence. It is a painful downfall for IPs that once defined cultural phenomena. We have gathered the stories of legendary games that plummeted into the abyss in an instant.

The Command & Conquer series, created by Westwood, laid the bedrock for the RTS genre and dominated the minds of PC gamers in the 90s. If Dune 2 established the RTS blueprint, C&C was the one that standardized it. The franchise recorded cumulative sales of over 30 to 40 million units, and the 1996 title Red Alert shook the entire world. While Blizzard eventually shifted the landscape through the Warcraft series and StarCraft, this achievement was only possible thanks to the foundation laid by C&C.

Alas, this gargantuan IP was dissolved in the digestive juices of a massive predator known as EA. After being acquired, the developers endured a series of cruel fates, culminating in the 2010 release Command & Conquer 4: Tiberian Twilight. Fans were horrified when the franchise's symbols—base building and resource gathering—were gutted and replaced with a mobile base system. It received atrocious reviews and headed straight to the grave. Following the cancellation of Command & Conquer Online and the mass layoff of the development team, the series hit a bottom from which it could not recover. While the 2018 mobile game Command & Conquer Rivals received decent enough reviews, it is but a flickering candle compared to the sun-like glory of the past.

Making a meteoric debut in 2009, Angry Birds was the definitive mobile game of the early smartphone era. With its intuitive fun of pulling back a slingshot to smash piggies' houses, it hit a staggering 5 billion downloads. Expanding into films and theme parks, it even earned the nickname 'the Mario of the mobile era.' Developer Rovio was a global superstar that had the world at its feet, and everyone was eager to see how they would leverage this IP.

However, in subsequent entries, Rovio began stuffing the series with heart systems, gacha, and P2W monetization, effectively corrupting it. In a display of pure defiance, when players continued to play the original paid 'Angry Birds Classic' rather than the monetization-heavy new releases, Rovio committed the blunder of forcibly deleting the original from stores. It was essentially a power struggle against their own fanbase. Eventually, Rovio was acquired by Sega in 2023, meeting a bitter end. Under Sega's wing, the series is shifting its focus to merchandise and films alongside Sonic, but whether it can ever truly revive as a game remains a mystery.

In 2009, PopCap’s Plants vs. Zombies elevated the tower defense genre from niche mod-territory to the mainstream. The quirky plants and adorable zombies were well-received, and the game was enjoyed by everyone from hardcore gamers to casual players. Back then, we all thought these cute plants would guard our gardens forever, and that the popularity would lead to endless animations and films.

But in 2011, the horror began when PopCap was acquired by EA (again!). The sequel, Plants vs. Zombies 2, introduced excessive F2P monetization, and controversy erupted over the firing of the original creator, leading to a rapid exodus of the player base. While the second game looks tame by today's standards, the third entry, which amplified these issues, has been languishing on the operating table for years. It is a garden once filled with pure joy, now choked by monetization weeds. Even the spin-off series Garden Warfare received a death sentence with its third installment, leaving both plants and zombies to rot in a sad reality.

In the late 2000s, Guitar Hero offered the experience of feeling like a rock star with a guitar controller in hand, boasting immense popularity. The third entry became the first individual video game to exceed $1 billion in revenue. The physical guitar controllers, which were sold alongside the game, satisfied both the need for high-end hardware and the desire for collection, while collaborations with legendary guitarists had a massive impact on pop culture. There were countless bedroom Jimi Hendrixes wearing their fingers to the bone on those plastic controllers.

However, merciless milking brought the series to its knees. As soon as the boom hit, Activision flooded the market with dozens of titles in just two or three years, including Band Hero, DJ Hero, band-specific titles, and mobile spin-offs. Consumer fatigue reached its peak, and after infighting among the numerous titles, the market cooled instantly, causing revenue to crash. The lineage of the series was cut short, and the 2015 reboot, Guitar Hero Live, was effectively a failure, ending the franchise's life for good.

Released on the NDS in 2009, Love Plus was a revolution that fundamentally changed the concept of dating simulations. Before smartphones were ubiquitous, the idea of spending daily life with a partner and experiencing real-time events was so immersive it felt like a substitute for reality. Package tours to hot springs or beaches with the in-game girlfriend emerged, and in a famous case in Tokyo, a man even held an official wedding ceremony with the character Nene, creating a social syndrome.

However, the series walked the path of ruin with the 3DS sequel, New Love Plus. A storm of system issues, countless bugs, and balance problems erupted. Instead of acknowledging and fixing them, Konami played the 'thick-skinned' card, alienating the fanbase. After the core development team left, the mobile title Love Plus Every was launched to spark a comeback, but it suffered a massive disaster, entering maintenance for two full months immediately after launch due to server crashes. By the time it finally opened, the fans had already left, and the game ended its short life in less than a year. Thus, the girlfriends who once shook the era vanished into history.
