I don’t think thats how it works for copyright. You have to defend your trademarks to keep them but for copyright, you can decide who can use it rather arbitralily.
Especially allowing a release of an old game on platform you don’t support which would not really compete with you.
So you are clearly talking about trademark. A game design can’t be trademarked. Only the name. Yes, if the name could be confused, that could be an issue. Maybe the cover art to some extent, if it is trademarked.
But if the game origin can be confused, so what? No law against that.
