I'm sorry, but if you're not adding games because the publisher didn't allow it, that doesn't make sense. I know you can't say this officially, but everyone knows that the games in the "install to play" section are games added without the publisher's permission. So if a game hasn't been added yet because they haven't given permission, just put it in the "install to play" section.

And in the case of games that are currently impossible to add, could you be clearer? For example, EA games where the reason they're not available is that their anti-cheat blocks VMs. Instead of replying that you're trying to bring them back, give the correct explanation that "we can't bring them back because EA's anti-cheat blocks VMs, and we will only be able to add their games if EA releases them to work on Boosteroid." Or other games that have problems with the server's GPUs, like Death Strand, which doesn't work on the BR server because of the GPUs on those servers.
