iv bought maybe 20 disk games, namly, mechwarrior, command and conquer generals and c&c 3, starcraft 2, diablo 2.... freelancer (good game btw, not a whole lot of people have heard of it), ... HL2 (after which i devoutly bought 99% of my games through steam) battlefield 2..... far cry.... and thats about all the disk games i own, over my whole life, maybe 2 of them i bought this year...
the rest of my 150+ games i have on steam
my old computer had 3 DVD drives so i could install games with less 'insert next disk' prompts and so i wouldnt have to switch out disks when getting on a different game
my current one has 1, and i only needed it to install the OS, for starcraft 2 (dam u blizzard, and i hate ur website), and when i want to play some mechwarrior 4
(to be honest, there are more disk games that i own on that list, but most of those are **** that i cant remember, and i bought them ages ago, and my only console is the PS2, do have some good games on that, but i rarely use it anymore due to my comp)
