I took part in many playground console arguments. All of them fuelled by my green eyed jealousy. I had a Megadrive but secretly always wanted a SNES. Then I had a Playstation (which I loved dearly) but envied those who had Goldeneye, Perfect Dark and Zelda.
Like many I own 'em all now 'cos I cant miss those exclusives.
Gears of War 2 and MGS4 being great examples of what you could miss owning one system.
