^ You actually make an amusing point about the developers not seeing any of that second hand sells money. There is/was a big guilt trip movement aimed at piracy (don't get me wrong, I really don't support piracy) that made the claim pirates are essentially robbing developers of money they deserve (true, but I think it is over played), yet nobody really cries out against the used game market (or used music market) that does the exact same thing. A lot of people will gladly buy used to save $5 or $10 dollars, if that game changes hands four times while it is in that premium price range, that is four or five brand new copies that the developers very well may have lost money on thanks to the recirculation of a single copy. Here I think one could easily make the claim that the second hand market is as or more detrimental to sales of video games, movies, and music as The Pirate Bay and other torrent sites.
And another topic your comment made me think of is the price of used games. Assassin's Creed II has only been out for a little over a year, yet it can be bought new for around $20.00 already (in fact, I purchases my copy for $17.99 back in December, when it was just over six months old). Left 4 Dead 2 has been out for about a year and a half, and it can already be found readily for $15.00. Fallout 3 just recently made a huge price drop, but prior to that it spent a steady couple of years dropping no lower than $30 for used copies, yet Fallout: New Vegas has only been out for a little more than six months and has only had one of eight planned DLC packs released for it, and it is already $20.00 brand new (man, do I regret buying that on release day!) Assassin's Creed: Brotherhood has been out since last November, yet it is still $55 brand new. Typically Halo games take years to come down in price, but Reach (another game I'll kick myself for buying near release) I've already seen used for $35.00 just around six months after its release. Meanwhile, Oblivion GOTY edition stays at a steady $40.00 used, despite being much older than any of the other games I've mentioned above. It is getting really hard to anticipate what games will keep their value and what ones will take major value plummets. The latest Medal of Honor game which has received really poor reviews and sales, but I'd still kind of like to play anyway, stays at a steady $50 range for a used copy, despite the fact that every store I go to has several used copies in stock.
The only game I bought new over the last year that isn't almost worthless now resale wise is CoD: Black Ops. Unless it is something like CoD or L4D that I will play a lot with friends online, I think I need to be done buying games that are anything newer than six months to a year old. Unfortunately, as much as it pains me to think of waiting, I think that needs to include the upcoming Portal 2 (I felt kind of burnt that Valve's previous release, Left 4 Dead 2, seemed to constantly go on sale for $20 off regular price within a month after its release, might wait to see if Portal 2 does the same. On one hand Valve is absolutely awesome at giving excellent deals on their games, but on the other hand it feels a bit like a kick in the mouth to those loyal fans who support them and buy their products shortly after release).
