@m627 Pre-installed games cannot be favored because they are on a read-only partition, this was done to facilitate users who, as soon as they installed the system, excluded all pre-installed games to maintain only a personal selection of games, so the developers created the option to hide pre-installed games.
You'll notice that these games can not be deleted or edited in general.

I highlight that it is not possible to hide all pre-installed games, as you can see here:

But, from what you mentioned, you want to favor DOOM and Quake, I recommend that you add the full version of these games, and favorite the full version. See if this helps:
