Honestly, I hate that the industry is full of entitled idiots...
Makes me feel bad that game development is the closest thing I have to a career skill.
Cliffy, seriously. Get a clue.
Second-hand sales have been a part of life for products as far back as people have been making things.
If the development budget and marketing costs for game development are so high that you need to prevent second hand sales to make a profit...
then guess what? It's not second hand sales that are the problem, it's you.
Being a producer of something does not give you a free pass to demand whatever you like.
All this constant whining does is prove the point I've suspected for ages:
Copyright laws encourage monopolistic behaviour, and are fundamentally broken.
(But, unfortunately, good luck fixing that while maintaining a capitalist economy...)
Where else but a monopoly could you start making such insane demands that imply if your development costs exceed your income, it's your income that needs to go up, and not your expenses that need to go down? And then try and forcibly increase your profits using such anti-consumer methods?
This is only possible when both the laws and means of enforcement are completely out of balance...
