best...game...ever,if you want to experience some truly epic, im still trying to set my mind to normal
as for the game play,
its more smooth and the UI is more easy to use then ME1, the exploration of other planets also had a big boost to it no more wasteland planets where you drive around in the mako, but lush and diverse areas ranging from a crashed ship between rocks to a scare mine and just able to explore it on foot(within boundaries of course), the only thing miss in this game is that its not big enough to feed me,in cities your still only able to be in a few small parts of it, but hey we cant have like a few hundred planets with cities as big that it would take years to visit them all :P
