Think about how different gaming looks today compared with a few decades ago. Open-world adventures, online multiplayer, mobile games, esports, sandbox worlds and battle royale matches are now completely normal. But many of these experiences were shaped by a handful of influential titles. These are games that changed the gaming industry by introducing new ideas, reaching new audiences or completely changing what players expected from video games.
Some games changed gameplay. Others changed technology, business models, platforms or gaming culture. From Super Mario Bros. and Doom to Minecraft and PUBG, these most influential video games didn’t just become successful, they helped shape the future of gaming.
Let’s look at 10 games that left a lasting mark on the video game industry.
1. Super Mario Bros.
Released: 1985
What Changed: Platform gaming and console game design
When Super Mario Bros. arrived on the Nintendo Entertainment System, it helped establish a blueprint for platform games that developers would follow for years.
Its carefully designed levels, memorable characters, power-ups, hidden areas and progressively challenging gameplay showed how much could be achieved with relatively simple controls.
Why It Mattered
Super Mario Bros. demonstrated the importance of polished game design, memorable characters and satisfying progression. It also helped strengthen Nintendo’s position in the console market and became one of the most recognizable games in gaming history.
The influence of classic platformers can still be seen in simple browser games today. For example, games such as Wothan Escape on OnlineKheladda use straightforward controls and progressively challenging obstacles to create an easy-to-understand but engaging experience.

2. Tetris
Released: 1984
What Changed: Puzzle gaming and accessible game design
Tetris had an incredibly simple concept: arrange falling blocks to create complete lines. Yet that simplicity became its greatest strength.
Unlike games that required complicated controls or lengthy tutorials, Tetris could be understood almost instantly.
Why It Mattered
Tetris showed that innovative video games didn’t need complicated mechanics to become successful. Its accessibility helped puzzle gaming reach audiences across different ages, countries and gaming platforms.
That same principle continues to work in modern browser gaming. Simple puzzle titles can be picked up within seconds, making them ideal for short gaming sessions.

Released: 1993
What Changed: First-person shooters, multiplayer and PC gaming
Before Doom, first-person games already existed. However, Doom helped establish many of the conventions that would define FPS gaming for years.
Fast movement, powerful weapons, enemies, atmospheric environments and intense combat created a formula that countless developers would build upon.
Why It Mattered
Doom’s influence went beyond gameplay. Its multiplayer modes and mod-friendly design encouraged new forms of PC gaming and player creativity.
Its shareware distribution model also offered an innovative way to get games into players’ hands.
The fast-paced shooting style it helped popularize can still be found in modern browser games such as Zombie Shooter and Shoot Robbers, where quick reactions and combat are central to the experience.

The term “Doom clone” became commonly used for first-person shooters that followed the game’s formula during the 1990s.
4. Super Mario 64
Released: 1996
What Changed: 3D game design and camera systems
Moving from 2D to 3D was one of the biggest transformations in video game history. Super Mario 64 showed developers how a platform game could work in a three-dimensional environment.
Its free movement, large levels and innovative camera system created a new standard for 3D game design.
Why It Mattered
Super Mario 64 helped establish ideas that became important parts of modern gaming, including analog movement, camera control, exploration and three-dimensional level design.
Its influence can still be seen in modern platformers, adventure games and exploration-focused titles.

5. Grand Theft Auto III
Released: 2001
What Changed: Open-world game design
Grand Theft Auto III transformed how players experienced virtual cities.
Instead of simply following a linear sequence of levels, players could explore a large 3D city, complete missions, discover side activities and interact with the environment.
Why It Mattered
GTA III helped popularize the modern open-world gaming formula. Large maps, side missions, exploration and player freedom eventually became common features across action, adventure and role-playing games.
It remains one of the most influential video games when discussing open-world game design and the evolution of modern gaming.

Released: 2004

World of Warcraft wasn’t the first MMORPG, but it brought the genre to an enormous audience.
Players could create characters, explore a persistent world, complete quests, join guilds and interact with thousands of other players.
Why It Mattered
World of Warcraft demonstrated the power of persistent online gaming communities. A game didn’t have to be something players simply completed and put away. It could become a world they continually returned to.
Its success influenced MMORPG development and helped shape expectations around long-term online multiplayer gaming.
The idea of returning to a game for short sessions, progressing over time and competing or cooperating with other players can also be seen in many modern browser games.

7. Angry Birds
Released: 2009
What Changed: Mobile and casual gaming
Before smartphones became major gaming platforms, many people didn’t think of their phones as gaming devices.
Then came Angry Birds.
Its simple controls, short sessions and instantly understandable gameplay made it perfectly suited to touchscreen devices.
Why It Mattered
Angry Birds helped demonstrate the potential of mobile gaming and casual games. It showed developers that smartphone games could reach people who might never consider themselves traditional gamers.
It also proved that a simple video game could grow into a much larger entertainment brand.
This shift is especially relevant to browser gaming today. Games such as Snake and Ladder, Traffic and Funny Animals Match3 show how simple mechanics can work well for players looking for quick and accessible gaming experiences.
Did You Know?
Angry Birds was Rovio’s 52nd game, meaning the company had already released dozens of titles before finding its breakthrough hit.
8. League of Legends
Released: 2009
What Changed: Free-to-play gaming and esports
League of Legends helped popularize a business model that would become extremely important in modern gaming: free-to-play gaming supported by optional purchases.
Instead of requiring players to purchase the game upfront, League of Legends allowed players to enter the game for free.
Why It Mattered
The game’s success demonstrated that competitive games could build enormous communities around free access, regular updates and optional purchases.
It also became a major force in the growth of the esports industry, helping competitive gaming develop into a global spectator experience.
The free-to-play model later became common across PC, console, mobile and browser gaming.
Did You Know?
League of Legends helped establish the idea that a game could continuously evolve through updates rather than remain a fixed product after release.
9. Minecraft
Released: 2011
What Changed: Sandbox gaming and user-generated content
Minecraft gave players something unusual: a world where creativity could become the main objective.
Instead of forcing everyone through the same story or set of missions, Minecraft allowed players to build, explore, survive and experiment.
Why It Mattered
Minecraft helped push sandbox gaming and player-generated experiences into the mainstream. It demonstrated that players could become creators rather than simply consumers of game content.
That idea continues to influence modern games built around creativity, exploration and user-generated content.
Even simpler browser experiences can use the same philosophy of giving players freedom to experiment. Games such as Hexa Match and Train Blocks on OnlineKheladda, for example, let players focus on problem-solving and experimentation rather than following a traditional story.
Did You Know?
Minecraft’s block-based visual style became one of the most recognizable aesthetics in modern gaming.
10. PUBG
Released: 2017
What Changed: Battle royale and large-scale multiplayer gaming
PUBG helped take the battle royale concept from a relatively niche idea to a mainstream gaming phenomenon.
Players were dropped into a large map, searched for equipment and competed to become the last survivor.
Why It Mattered
PUBG helped establish battle royale games as one of the biggest multiplayer trends of the late 2010s. Its success inspired numerous developers to experiment with the format and influenced the direction of online multiplayer gaming.
The battle royale formula eventually became a major part of gaming culture and helped shape some of the biggest multiplayer releases that followed.
