I feel if a there are a lot of people who prefer physical games, and there are affordable memory cards and disc for storing PC games, selling physical PC games maybe popular again. There is always a chance that some countries blocks Online PC game download stores like Steam, and GOG, so gamers who want to buy the game would need to buy a physical copy of the game because the government blocked game buying websites. The government in some countries can shutdown the outside internet, so physical games maybe the only way to play games which you have not downloaded before the internet shutdown in a country. More PC games like Fortnite and League of Legends are now free to play, so I feel these companies may someday make physical copies of the games to give away at a public place like college or by mailing the games to people's homes, so more people can play the game, and hopefully, spend money on DLC, game mods, paid characters, and in-game money. There are probably some PC Gamers who may buy a Physical PC Game to also collect the PC game boxes, manuals, artwork, and toys which come with the game.
