There's also the question of whether an unsigned post-purchase EULA constitutes a legally binding contract at all.
It is, if you buy the disk, install the game and then click through. It ain't if you download Origin, install, accept the EULA and then buy a game.
Still, it is questionable whether a contract that is rarely read and can be changed at whim is a contract in some legislations at all. This is still a HUGE open topic.
When they haven't found them legally binding, they've generally either been simply ridiculous or deceiving.
