I guess I'm a hoarder. I never "trade-in" but I used to sell sometimes when I had less money. Now I'll just "lend" my games to friends indefinitely. My collection is pretty broad and extensive. While I usually buy new (except for keeping rental games on occasion) I will very rarely pre-order a title. If I do it has to have some sort of premium (bonus dlc or an art book or something) and I have to be pretty damn sure it will be outstanding.
For example, I was addicted to the Just Cause 2 demo so when bonus dlc was announced, I pre-ordered. I loved fallout3 so when bonus dlc was announced for New Vegas, I pre-ordered.
