It is awesome.

But I have a question. is there a standaralone OpenRA...such as OpenTTD? Well, I say is there a free pack of graphics, sounds and other data (licensed under CC or GPL)? or it is necesary the old games.

Bye.

No, there is no libre graphics set for OpenRA.

There is a stand-alone game in the works however which might be libre: http://www.moddb.com/mods/nomad-galaxy
