If he bought Cod4 at launch he could easily have sold on his copy... his post doesn't seem to make any sense at all.
He refers to games he can still sell on. And then he states someone wouldn't downgrade from a GTX680 to a 570???
Linktoinsanity, what are you trying to say with that statement which is purely circumstantial?
If you had bills to pay and your pc was increasing your electric bill and a friend offered to trade cards with you, would you not do that or would you rather be locked in because Microsoft/Nvidia/Steam say you are not allowed to make changes in ownership...
And before you say that isn't a related issue, it can be. Say you pre-ordered Heart of the Swarm, and it came out tomorrow, and the day after your bills came in higher than you could cover. Nope sorry, you can't sell that to make up for your mistake as it's locked to your account, you'll just have to go homeless, but on the bright side you still own that game you got to play for a short period

Also, some people buy retro games, and some people only buy recently released games. But there are people who buy old hardware or old consoles, so I still can't see how the point you are trying to make stands up?
Games are just another piece of entertainment/material wealth. Of course you should be able to sell on things you no longer want.
