I had no problems getting it or installing (cable).
I've only played the tutorial and a brief match against the computer, but I'll give this quasi-review.

The graphics seem a little less than what I've come to expect in new games but they're not bad. To rotate the camera you have to hold alt and move the mouse and mousewheel zooms. I don't think you can remap those keys either (it said those controls were "locked"). Like most games with this feature there's no reason to zoom in, and having to hold down alt makes rotating a hassle. A right mouse button or keyboard keys would have been better.

The creature creation system is brilliant. You can only combine two animals but each body part has unique properties (speed, defense, offense, etc). You can choose which body part from each animal you want, resulting in thousands of possible combinations. The body parts are head, back (torso?), front legs, back legs, tail.

I found it was far too easy to collect electricity. I always had a huge surplus. Electricity and coal are the resources used. Lots of little things were annoying too but will probably be fixed in a patch. Setting waypoints from a building can't be done by right clicking. If you tell your guys to attack a group of enemies they'll run around trying to attack the specific creature you targetted (probably solved by attack moving..). I expected more micromanagement too, something similar to WC3 maybe. It's more of a mass produce and rush game. There are a few special abilities though, like the eel's electric shock sphere thing (which damages your units too).

Uh..I'll stop writing now. Creature creation is awesome. Gameplay is "meh". Mind you I haven't tried the solo campaign or a multiplayer game yet.
