Warcraft III: The Frozen Throne is a real-time strategy video game that puts players in control of a group of units and buildings in order to achieve a variety of goals
The expansion fine-tunes the gameplay of the main game rather than changing it
The food limit and the upkeep requirements, which dealt a penalty on resource gain when too many units were active at the same time, have both been increased slightly, leading to the ability to mobilize somewhat larger and more powerful forces
The cost of buildings has been decreased as well, allowing for a quicker start of the game
The weapon and armor type system has been completely revamped and a lot of units have had their weapon or armor types changed, and the weapon types are effective and ineffective against different armor types compared to Reign of Chaos
