Warcraft III Pre-Installed Game
Tower Defense (TD) maps were very popular map creations and probably helped spawn the basic idea for future games like Clash Royale. One of the most famous products of the War3 custom mapping scene was the Aeon of Strife (ported from Starcraft: Brood War) and the resulting legendary Defense of the Ancients (DotA) map which spawned so many Multiplayer Online Battle Arena (MOBA) style of games. Without the popularity of Warcraft III and the included Warcraft III Map Editor, the online gaming landscape would look very different than it does today.
