Wing Commander III - Free on Origin right now.

Despite being generally not well liked by the gaming public, EA is still attempting to get people to use it's platform 'Origin'. They have been giving out games free for people to add to their origin accounts lately. So far, some past games have been Peggle, Sims 2, and Plants vs Zombies.

Now they are giving away the epic space adventure Wing Comander III. This comes complete with cut scenes of Mark Hamill talking to giant cat puppets, and some of the finest space sim combat. Even though Origin is a derp and a half, this is a good game worthy of bothering. Grab Origin and get it while you can.
