That's bull. Money from used games does go to the developer. For it to be used it at one point must have been new. It must have been bought by someone at some point. For every used copy of a game that exists money from that has made it to the developer, no matter how many times it gets resold. And that is all they are entitled to. And you do have a right to complain about a game if you bought it used. You experienced the game, and you have an opinion about it. Just because you bought it without a plastic film on it doesn't mean your opinion isn't valid. And developers should listen to that opinion. No matter how you bought a game, if you liked the game enough for there to be a chance you will buy a sequel then developers will be very interested in how they can improve the game to make you guy the next one. And if you already have experience with a series and hear about improvements to a sequel then you are far more likely to buy it new. And even if you don't buy it new a developer will want to know what people think so they can attract any new customers.
