I did the trial. The client is 4gigs and you need a fast processor to really enjoy the game, i.e. the better your PC the more you will get out of the amazing graphics capability. The game itself is soooo freaking big and complex that its hard to wrap your head around at first. There is just so much to it. Huge storylines and background histories and so many people playing. Its worth a shot to see if you will like it. I gave up after the trial, ogame is more my speed. lol
