Advise game on the space theme

Watched all eight seasons of the new Doctor Who and I was again covered with a longing for the stars and the dusty paths of distant planets. Do not let the fourth day, soon on the moon start to howl.

Please advise game in the genre of science fiction taking place in space, on several planets, RPG, shooter or action game, the graphics are not too important, if only it was beautifully drawn, at least at the level of the second Kotor. And I have to re-think the first Mass Effect and both involved, and if does not help, then re-subscribe to eve. I would be very happy if someone knows games like ME and KOTOR.
