Blizzard Entertainment is a top tier developer and publisher of games, and has an amazing pedigree including some of the industry’s most critically acclaimed games, including World of Warcraft®, Hearthstone®, StarCraft®, Overwatch® and Diablo®. But which one game makes Blizzard the most money?

Blizzard all time Game Sales Chart!

Number 1 top selling Blizzard game!

The best selling game from the Blizzard stable to date is the mighty Overwatch® with a colossal 50 million copies sold over 3 years according to a Bloomberg report that was published in April 2022. The game made over $1billion in its first year of release!

The game tapped into a fairly new, but immensely popular trend among gamers and the public. That being esports, which not only engaged online multiplayer contests, but also spectating other players (a la twitch style).

It’s basically like being a professional sports fan (eg American football), only instead of watching actual people play American football, you’re watching people play digital characters online.

Overwatch 2 has been available since October 8th, 2023 and in the newer version of the game, the company is using the free to play model like fortnight. This move clearly paid off for them.

With Blizzard quoting “The October launch of Overwatch 2 with a free-to-play model delivered the highest quarterly figures for player numbers and hours played in Overwatch history,” showing the move to free to play has been a net positive for overall engagement for the franchise.

Diablo III [and Reaper of Souls expansion]

Diablo III and Reaper of Souls expansion ( 30 million sales respectively) is in second position in our Blizzard game sales ranking. Reaper of Souls adds a number of new features to the core gameplay of Diablo III. These include a new character class, the Crusader, who whos specialist skill is defensive play, new large weapons (including new types like flails), defensive kit like specialized “Crusader shields”, and of course, the mighty holy magic! Clearly this game was a huge hit with the gaming crew!

Diablo II

In third place; Diablo II sold a whopping 17 million copies! This sequel starts shortly after the final events of the original Diablo. This time a new hero needs controlling, and you must attempt to stop the destruction caused by Diablos return. This game has 5 acts ina variety of locations and has a bigger cast of characters to interact and play the game with.

World of Warcraft

The legendary world of warcraft comes in at 4th position in our Blizzard game sales chart with a hugely impressive 12 million subscribers at it’s peak. Simply staggeringly successful game (it is awesome though!). This classic is set in the fictional world of Azeroth. World of Warcraft lets players make avatar-style characters and explore a huge universe where they interact and battle with nonplayer characters (NPCs) **as in not real people** and of course other real-world players (PCs).!


In 5th place is Starcraft 11 million copies which is testament to how good this game was! The story is based on the activities of 3 different species who live in a section of the Milky Way which is called the Koprulu Sector. many millenia before the time the game is in, the Xel’Naga genetically engineer the Protoss and after that they engineer the Zerg while trying to create pure life form beings.

Starcraft II

Slightly behind the original game in total sales in 6th place is Starcraft II with 6 million copies sold! Artanis leads the Golden Armada on an invasion of their Zerg riddled homeworld of Aiur, which has lain abandoned since the Brood War began six years earlier.

Starcraft II Heart of the Swarm [expansion pack]

With sales of 1.1 million copies this campaign expansion uses a more RPG approach with Kerrigan being a controllable character in most of the missions and there is also some nice upgrades for the Queen of Blades and her entourage.

Starcraft II Legacy of the Void [expansion pack]

This Starcraft II expansion pack has sales of 1 million copies the Legacy of the Void concludes the StarCraft II trilogy, picking up where Heart of the Swarm ended.

Warcraft III: Reign of Chaos

In 7th place in the Blizzard all time sales list with sales of 3 million copies. Warcraft III is set a few years after the events that happened in Warcraft II, and is based on the Burning Legion’s attempt to take over the fictional land of Azeroth with an army of the Undead. The undead army is led by fallen paladin Arthas Menethil. It chronicles the combined efforts of the Human Alliance, Orcish Horde, and Night Elves to stop them before they can corrupt the World Tree.

Warcraft III: The Frozen Throne [expansion pack]

A highly regarded expansion pack for WoW 3. This expansion pack sold a whopping 3 million copies and comes in at 10 place in our chart.


Set in the world of Sanctuary and in the kingdom of Khanduras , Diablo lets your control a lone hero or heroine as you begine amission to free the town of Tristram of the titular Lord of Terror, and his horrible horde of demon minions lurking in the shadows within the Dungeon under the Cathedral which is located on the outer edge of the town.
