To be fair I didn't really give Mass Effect 2 much of a chance, I downloaded the PS3 demo and I just got irritated at the length of the unskippable cut scene at the start. Pllus when I watched my housemate play it (for the forth time through) it looked fairly linear. I have a real problem with linear games since I had the epic disappointment of Final Fantasy 13. 15 hours of walking down corridors before I gave up with it ruined my brain.
