The Warcraft game has moved on to a lot of PvP in luxurious environments, but I still like this game better, partly because you can effectively use terrain and build structures, and lead a large group of your design.
Another great RTS game from Blizzard. It's starting to show it's age, but still a great game with a huge campaign to play through with the possiblity to buy the expansion pack if you still want more. The game is possibly more known for it's multiplayer 1v1, but the campaign is still worth playing through!
