Assuming that the record companies couldn't just reclaim the rights as soon as they expire, right? No one should be able to claim it at that point. It should stay in public domain forever once it expires.
Even many owners themselves seem to have no problem releasing/forgetting about their old games and therefore stop caring about them. After 5 or 10 years, in less the game requires a subscription to play it'll be making little or no money anymore.
If you want to be even more fair, no one should be able to claim the rights to that game again after the time expires so that it can permanently stay in public domain. But there may have to be an exception for subscription based games, especially WoW which is still doing really good.
But I guess some companies are just that greedy and think their games will still be making money after 35 or more years, and just because they complained, that's what the rule is.
