There is no law that specifically settles the issue of digital content resale. Companies are using the loophole of the "communication to the public" clause of copyright law which is intended for broadcasting and public events. If there was EU law that directly contradicted game resale, then the ruling by the french court (assuming that France would have already incororated that law into it slegal system) would have been different.
I don't know what legal basis you're referring to specifically with the "communication to the public" clause, but everything regarding the Oracle case was based on EU directives, so the question could also be whether the relevant directives have been adequately transposed into national law.
Edit: so after having read the Usedsoft and Ranks & Vasiļevičs cases some more, I don't really see any basis to restrict game reselling if all the relevant directives are appropriately transposed unless, indeed, some sort of loophole is used. Games are software too. If all the conditions stated in Usedsoft apply, game reselling should also be possible. Indefinite or long term licenses make it so that effectively a product rather than a license is sold. None of the language used seems to imply that there is a difference between business or personal licenses. What strikes me most then is how long it's taken for this to end up trickling down to videogames. I guess because it's more difficult to resell something that's exclusively associated with an account log-in and as such tied to different games as well. You can't just locate your "license" from your account, delete said license and somehow transfer it to somebody else. I'm still unclear as to how it was possible for software to be "transmitted" for resale then in the Usedsoft case. My assumption would be product keys that aren't account-bound. So I guess one of the practical effects of the enforcement of this (case) law would have to be the ability to "liberate" licenses from accounts.
Edit 2: having now gotten a better understanding of Usedsoft, 2001/29 and 2009/24 through a reading of the e-book case, it seems like the French court didn't apply the 2009 directive on computer programs correctly and videogames probably can't be classified as 'computer programs'. This + some of the conclusions from C‑355/12 make it so the resale of games will be highly unlikely, if the AG's opinion is followed in the e-book case.
