Universe at War: Earth Assault demo

A new RTS pc (and console) release (slated for Dec) with three alien races.
They fight each other and Earth is the invaded "3rd world country" where the
fighting takes place. Humans do attack you, but they're kind of like insect
pests.

I tried the demo and even though the graphics, sound effects, and voice
acting are pretty damned good, I don't know if there's enough here to
warrant a buy. Looks like a Sega A-title which will probably go for $50-55
suggested retail.

The demo consists of a really high-quality intro movie and two Hierarchy
faction missions (save function disabled). Neither mission is challenging
and I don't really know that much more about the game after playing them.

One neat thing is the Hierarchy Walker.....an awesomely humongous and
upgradable war-machine, which is kind of like a moving base.

Anybody else tried the demo and have an opinion?
