The Frozen Throne provides gamers with a vast new chapter in the epic Warcraft saga. In the single-player campaign, players revisit the war-torn world of Azeroth. Several months have passed since Archimonde and the Burning Legion were defeated at the battle of Mount Hyjal, yet a new threat has arisen throughout the land. One new Hero per race, each possessing powerful spells and magical abilities. A host of new units, each equipped with new abilities and spells, giving players the opportunity to create diverse strategic and tactical forms of combat. Player-built shops, unique for each race, equipped with items carefully designed to improve and aid the units of every race. Neutral Heroes, available for recruitment by all players, that can supplement and strengthen a player's army with all new spells and abilities. Expanded multiplayer options over Battle.net including multiple new game types, clan and tournament support.
Warcraft III, If you have not heard of it, you've been living under a rock.
This game is fantastic. Not just the game as it shipped, but also the game it came to be.
Let me explain why: The good: - THE BEST EDITOR. Seriously, if you like modding, it'll never get better than this. - Thousands of custom game modes to enjoy. You can play Dota here. Nearly all of the game modes are polished. - An active and vibrant community. There are lots of people working on all kinds of projects, everyone will be happy to help you along! - A huge story driven campaign that sets off the events in World of Warcraft.
The bad: - The RTS speed might turn you off. Its rather slow. - The engine cannot handle too many units at the same time, and lag will only hit those who own too many. (I guess it also functions as an auto-balance tool ;) )
