Another cult series on the list is the latest entry in the legendary StarCraft. Released in 2010, StarCraft II is once again about the relentless struggle between Protoss, Terran and Zerg. Supported by two additional packs in the following years (Zerg-focused Heart of the Swarm and Protoss-focused Legacy of the Void), the first Terran-focused part of the game, Wings of Liberty, has been made free-to-play since 2017.
