Yeah, there are probably even more cases that should be listed in the poll, but it's mainly meant to inspire discussion anyway.
Also missing is: all of the above. Also missing is: printout of rules and DiY/PnP box.
If I have (say) a German version of a game, and the .pdf of the English rules is available, I will supply a professionally printed English copy.
If I were selling a re-theme or DiY make of an OOP game I'd supply a box of some kind too. IANAL but pretty much the only thing that can be copyrighted is the artwork, not the theme or the concept or the rules.
Trademark issues may also be relevant in addition to copyright, like the recent Heroquest situation showed.
