Lot of years and till the best...
Warcraft III is an amazing game. The story of that game is very interesting and take you deeply in the game that you won't want to stop playing sometimes. The hero are well done and the spell and movements are fantastic. For all the years since Warcraft III have been created and its still one of the best strategy game in the world and i'm sure will remain the best.
The Graphic are maybe out-dated as it not the same graphic like Crysis, Half Life 2 etc.... but definitely it is a very good one and it have still a good proposal to the players. Even the game is pretty old, day by day the game is more popular due to what is contain is fantastic. Blizzard have been respected for that game as it is a good hitting RTS game.
So if you don't have the game please buy it and play it you won't regret i'm sure you will be addicted to it very fast.
