I always want to own the disk.
But I should clarify
"Games for windows" install problems
Buying used game, how can I use it or they are selling them, but theoretically cannot be used due to the key is already taken ?
I would see tons of complaints if those disks didn't work, so how are they doing it.
I want to sell a ton of stuff I have, but since steam , those games means they can't use them,
I think it is illegal to not be allowed to sell your old disks. I can't hand them my email so they can log in.
