i know me too. i think i might get a 500 GB HDD to replace my 160. I should have just shelled out the 50 extra dollars for the 320 when i bought my ps3. I had no idea that games were so big.
DVD games (multiplat) have 4-7GB... Blupray games (exclusives) have 10-15GB.
Retail games of course... PNS only games have way less GB (1-2GB).
