You bring up a great topic! Game development has gone up year over year yet the cost of games for the most part have not. This is why developers have turned to alternative business models in order to turn a profit. Trade ins at companies like GameStop etc and buying used don’t help developers one bit, 100% of that money goes to gamestop so developers (manly AAA) look for ways so that we keep the game longer and put more money into it as we go (games as a service model) or we could just pay more upfront but I’m guessing we’d all bitch about that, won’t we.
