Avoiding the anti- corporate diatribe bandwagon for one moment ;p. I generally buy one game, play it to death (eg Deus Ex), then trade it in for a new copy of a game that I want (in this instance, Dark Souls). I lack the resources to maintain a library of games, many of which I no longer play, and try to support developers that appeal to me as much as possible. I am by no means poor, but I do play a lot of games, and this limits the extent to which I can pay full price. I have also lost count of how much I have invested in various mappacks (though this is decreasing) and song downloads for rockband (equally so). Nothing wrong with buying second hand...just make sure that your ratio is healthy D
