It's been eleven years since Blizzard released Warcraft III. And since it doesn't look like we'll be getting an RTS sequel any time soon, a Chinese fan has gone and made himself one.
What you're looking at here is World Of Warcraft RTS: Alliance vs Horde (what was wrong with Warcraft IV?), a modified take of StarCraft II that looks a little rough, I'll grant you, but gets an A+ for effort.
If you've got StarCraft II, you can download it yourself and give it a try (it's around 150MB). Just go to SCII's arcade and search for "Alliance and Horde", it should pop right up.
