You of course realize, not all contract terms are binding, yet when contract terms are implemented in software, they become much more binding than when they are interpreted by a court of law.

You also realize that not all license agreements are the same; and first sale doctrine normally gives right to resell copyrighted works. I would in effect be gifting the game to my girlfriend, rather than lending it, as I wouldn't be playing it again.

And thanks for accusing me of breaking the law. I appreciate it.

(The thing that tipped me into buying the game on Steam was that I'd also be supporting independent developers with the Potato Sack etc.)
