Few of the games i am really looking forward to, I pre-order only when they are available for $45-47 range. Once I am done with it, I sell it off on Glyde or Ebay. The rest of them, I buy on ebay when they are available near $35. That is a more sustainable model for me because I end up spending only $10-15 per game, getting most of my money back by selling the game back and holding on to the few that i really like.
I know this does not help the developer but I just cannot afford $60 per game. I do know that if the games where priced more reasonably around $45, I would buy more games immediate after release instead of waiting for the price to go down in the resale market though that might not be true for most people.
