First off, I and I alone decide how and where to spend my hard earned dollars, not you. You are not entitled to my wallet and you are not entitled to decide my purchases. Your job as a business is to, 1, create a compelling product that I would want to purchase and 2, setting a price for that particular product and how, where I can purchase it. These are the only two things that I care about when you release your product. I dont care how much it cost you to make and I dont care how long it took you to make it. These are not my problems; they are yours and yours alone.
If you have a problem with used games, dont whine and moan about it and plead gamers to not buy used but buy new. We dont care to hear it. We as the consumers will part with are money how we want to part with it; you are not the decision maker. What you can do is decide how you want to release your games. If you want to put drm on your game, make it online only, digital download only or throw a cd key in the box, thats your propagative and thats your right. Our right is also to not purchase your game based on those factors no matter how much you bitch about it. If we buy your game used, Oh well, go bitch about it to your friends or your boss. Dont bitch about it to us gamers; we value our money more than your feelings. Sorry.
