Here are a few ideas for an indie game based on the World of Warcraft universe:

A side-scrolling adventure game where the player takes on the role of a rogue character, sneaking through dungeons and engaging in stealth combat. An action RPG where the player controls a party of characters, each with unique abilities, as they explore the world of Azeroth and undertake quests. A strategy game where the player builds and manages a settlement, recruiting heroes, training troops, and engaging in battles with enemy factions. A puzzle game where the player takes on the role of a mage, using spells to navigate through a series of increasingly difficult challenges. A survival game set in the wilderness of Azeroth, where the player must gather resources, craft items, and defend themselves against dangerous creatures. A card game where players collect cards representing heroes, minions, and spells, then use them to battle against each other in duels. An open-world sandbox game where the player can explore the vast world of Azeroth, undertake quests, and build their own custom adventures using a powerful scripting tool. Remember, these are just ideas, and you can always come up with your own unique spin on the World of Warcraft universe to create a truly original and exciting indie game.
