Darkspore

Darkspore is a sci-fi action role-playing game, based partially on the 2008 video game Spore. It is described as "a fast-paced, sci-fi Action-RPG in which the player battles across alien worlds to save the galaxy from the mutated forces of Darkspore.". The game was released on April 26, 2011, for Windows. It features a similar version of the award-winning real-time character creation and editing technology first seen in Spore. However, unlike Spore, players cannot create characters. They can, however, edit certain characters, to a limited extent though.

Demo version
There's a demo version available (EA account required). It is accessed by downloading Darkspore from their official site (download is free, the key is what costs money), logging-in, and selecting 'Play Demo'. It's just like the full game, except the player can only reach Crogenitor Level 9 and play up-to Darkspore Threat 2-2.

Limited Edition
On November 3, 2010, the main Darkspore website was updated with new, drastically different graphics and layout, a Tumblr feed, and an offer to pre-order Darkspore to receive a Limited edition version that would immediately unlock the unique Quantum Ravager, called "Maldri, the Quantum Raider", along with 3 exclusive stat-boosting items, one with a stat the occurs nowhere else in-game.

This offer expired on January 31, 2011, but unsold copies of the Limited Edition can still be found in various places that sell games.
