What makes a video game truly great? Sales figures matter, but so does cultural impact, innovation, and whether the game still feels magical decades later. This list weighs all of those factors to celebrate the ten games that defined the medium.
Created by Soviet programmer Alexey Pajitnov, Tetris is the best-selling video game of all time with over 520 million copies sold across all platforms. Its genius lies in its simplicity: rotating falling blocks to complete lines. There are no characters, no story, no enemies — just pure, elegant mechanics that tap directly into the human brain's love of order and pattern recognition. Tetris has been ported to virtually every platform ever made, including programmable calculators and oscilloscopes. It's not just a game; it's a mathematical proof that simple rules can produce infinite depth.
Markus "Notch" Persson built Minecraft as a solo side project; it became the best-selling individual game title in history with over 300 million copies sold. Its open sandbox — where players mine resources, build structures, and survive nights filled with monsters — captured something no game before it had fully unlocked: the joy of creation without limits. Minecraft is now used in classrooms to teach history, mathematics, and coding. Entire architectural schools have held design projects inside it. Its cultural footprint rivals any blockbuster franchise.
When the video game industry collapsed in 1983, Super Mario Bros. was the game that brought it back. Designed by Shigeru Miyamoto for the NES, it established the grammar of the platformer genre and introduced design principles — rewarding exploration, layered difficulty, responsive controls — that developers still follow today. Mario himself became the most recognizable video game character in the world. More than 40 years later, Mario games are still system-sellers.
Ocarina of Time holds the highest aggregate review score of any game ever released on Metacritic. Nintendo's leap into 3D gaming was so masterfully executed that virtually every 3D action-adventure game made in the 25 years since has borrowed from it: lock-on targeting, context-sensitive actions, and a structure that seamlessly weaves exploration, puzzle-solving, and combat. The world of Hyrule felt genuinely alive in a way 3D games had never managed before. It remains the standard by which adventure games are measured.
Namco's Pac-Man was designed specifically to attract players who weren't interested in the space shooters that dominated arcades in 1980 — particularly women. It worked spectacularly. Pac-Man became the first video game to cross into mainstream pop culture: there was a TV cartoon, a hit pop song ("Pac-Man Fever"), and merchandise everywhere. The game itself generated an estimated $2.5 billion in quarters during its arcade run. It introduced the concept of the video game character with a recognizable personality, paving the way for every gaming icon that followed.
With over 195 million copies sold and approximately $8 billion in revenue, GTA V is the most commercially successful entertainment product in history — surpassing every film, album, and book ever made. Its open-world recreation of Los Santos (a fictional Los Angeles) set a new standard for virtual city-building. The addition of GTA Online extended its life indefinitely, with players still actively building empires and causing chaos over a decade after launch. As both a technical achievement and a cultural document of early 21st-century America, it stands alone.
Naughty Dog's The Last of Us proved that video games could deliver storytelling on par with the finest prestige television. The relationship between Joel and Ellie, built across a post-apocalyptic cross-country journey, reaches emotional depths that most films never approach. The game was adapted into an HBO series that became one of the highest-rated shows of 2023 — a testament to how fully realized its world and characters are. It changed what the industry believed games could accomplish narratively.
Valve's Half-Life 2 earned a 96/100 on Metacritic and won over 39 "Game of the Year" awards. More than scores, it revolutionized first-person game design by weaving story into gameplay rather than interrupting it with cutscenes — a technique that became standard across the industry. Its physics engine (Havok) was so advanced that entire gameplay puzzles were built around it. The gravity gun became iconic. Half-Life 2 set a technical and creative bar that shaped FPS design for the next two decades.
FromSoftware's Dark Souls invented a new genre. Its brutal difficulty, environmental storytelling, and interconnected world design inspired a wave of "Soulslike" games from dozens of studios. More importantly, it demonstrated that punishing players — demanding patience, precision, and learning from failure — could be its own form of reward. Dark Souls trusts players to figure things out, a design philosophy that became a movement. Games like Hollow Knight, Sekiro, Elden Ring, and Lies of P all exist because of it.
id Software's Doom didn't just create the first-person shooter genre — it created the PC gaming industry as we know it. Shareware distribution made it the most installed piece of software on PCs in the early 1990s. Its engine technology was licensed by dozens of studios. It pioneered modding culture, with players building custom maps and campaigns that extended its life for decades. U.S. Defense Department soldiers trained on Doom. It's been ported to ATMs, pregnancy tests, and printers. Doom is not just a great game — it's infrastructure.
