I want to share to you a game called Darkspace
It is a free game for the pc that is based in space. It is a mmorpg and its really either fighting, defending or building.
Their are only two servers but they both are different.
First is the Metaverse which is in constant war!
By that i mean you could have captured a planet and left for 10 minutes to find the planet you captured is now captured by a diffrent faction.
