Space Engine isn't really a game, it's just basically a very pretty, very large 3D explorable photograph. If you had this kind of graphics+detail in an actual game you can play (not downgrading SE; It's an awesome thing IMO) eg. US2, then you would be right.
Wubbzy, if you think that the graphics in US2 are bad, then I would like to see you do better. GA have been working like dogs on this thing for more than 3 years and your'e complaining? Please don't, and be thankful you even get to see pictures of a new game that hasn't been publicly released yet (even better, you get to TEST AND PLAY THE GAME), unlike Half Life 3 and Portal 3, which have ZERO info leaked.
