Ask the developer of whatever game you're playing.

You can always do a google search.
Someone, somewhere has archived a copy of past versions.

But in the end, you are bound to the current EULA.

A EULA change usually causes whatever product or service to bring it your attention and gives you the option to agree to it. Some times the changes are spelled out, most times they are not. Unless the previous one was saved somewhere by someone, you'll only have access to the current one.

People love saving these on the Internet Archive.
