The real division between games and games will, as it always has been, be if the game is fun or not. Nothing else matters. If it's not fun, it'll flop and disappear, some quicker than others. But if it's fun, people will continue to play it.
This doesn't ring true, just for example "Among Us" sales only skyrocket after a famous streamer picked it up, the sales were below average before that specific event that happened by mere luck, and it was just as fun before he made it popular.
