I have a big collection myself but the only reason mine falls short of yours is because i want everything boxed and in great shape so i have to pay more for each game sadly :( and i dont display my non boxed stuff unless it goes with a theme, such as my snes games i have roughly 200 of these non boxed sitting in a crate in my closet and nearly 100 nes game as well in the same crate lol
Boxed stuff just appeals to me so much more for some odd reason.
