Dark_art_: On the other end, isn't GOG requiring to accept it's own EULA at every game install?
You're right. GOG's EULA contains some terms I don't like.
For example, section 11.1 says this: "Please follow these rules regarding the GOG services and GOG content. Please read these rules carefully since failure to follow them (particularly those in relation to cheating) will be considered a material breach of this Agreement, which could lead to suspension or cancellation of your access to GOG Services."
According to GOG's EULA, section 1.1, "GOG Services" includes "any games or videos or other content which you purchase or access via us".
Section 11.1 (g) says this "Don't do or say anything which is or may be considered racist, xenophobic, sexist, defamatory or otherwise offensive or illegal. Be nice to each other please!"
Not that I support racism, xenophobia, sexism, etc., but that should not be a valid reason to terminate the agreement. According to the agreement, GOG could take away your games if you say something offensive.
One point I will make in GOG's favor is that they differentiate between "GOG Services" and "GOG Content" in the agreement. Seemingly, the agreement allows them to stop you from accessing your games online, but doesn't allow them to make you delete games you already have installed or downloaded.
That's better than most EULAs, but I still don't love it. Consumers don't have unlimited space to keep all their games and installers offline, so in many cases revoking online access to the installers is the same as taking away the game entirely. This opens up other complicated questions, like "Is GOG required legally to host installers until the end of time?"
I would be curious to hear how GOG reconciles this agreement with their stated philosophy.
