A classic Activision IP, Crash Bandicoot is once again a hot property thanks to its recent revival. The N. Sane Trilogy and Crash Team Racing Nitro-Fueled remastered helped bring the series back, and the more recent Crash Bandicoot 4 has cemented it as an important Activision series.

While dormant for some time, Activision's Tony Hawk series resurfaced in 2020 with the release of Tony Hawk's Pro Skater 1+2, a remaster of the first two games. Its success means that Tony Hawk could well be an important series for Xbox.

Similar to Crash Bandicoot, Spyro is another classic Activision series that was dormant for quite some years. The Reignited Trilogy remasters proved highly successful, though, opening the door for more Spyro. In addition, Activision also owns the Spyro spin-off franchise Skylanders.

Guitar Hero hasn't been seen since 2015's Guitar Hero Live, but there's still a community that adores the once-dominant music rhythm series. Any potential revival is now in Xbox's hands.

Activision Blizzard also owns King, the mobile developer behind Candy Crush. An absolute powerhouse in the mobile gaming space, the Candy Crush games are played by millions of people across the world.

From the Blizzard side of the company comes one of the most recognisable fantasy franchises of all time: Warcraft. The series covers both the RTS games - the most recent of which is the remaster Warcraft 3: Reforged - and the long-enduring MMO, World of Warcraft.

Diablo is Blizzard's action RPG series, which blends aspects of horror with grimdark fantasy. Diablo 4 is currently in development, and aims to redefine the series after its predecessor, Diablo 3, faced mixed critical and player response.

StarCraft is Blizzard's science-fiction RTS series, and at one point was the vanguard game for the esports community. StarCraft 2 has pretty much reached the end of its extraordinary long life, but there's surely still more stories to be told about the Terran vs Protoss vs Zerg conflicts.

Blizzard's Warcraft universe is also the setting for Hearthstone, the studio's incredibly popular competitive card game. After dozens of expansions and reshuffles, the game remains a stalwart member of the CCG upper echelon.

Overwatch may be Blizzard's youngest game series, but its also one of its most successful. The team-based PvP shooter took the world by storm when it arrived in 2016, and will soon explore the world of co-op multiplayer with its sequel, Overwatch 2.
