> Games that are good, are going to be popular

Games that pass a certain quality bar and were designed with mass appeal in mind are going to be popular.

I've played at least a few live-service games that I consider good, but were shutdown due to lack of popularity. Some of them I can't even find client files for to start working on a server.

Value is subjective - tons of games that are now considered cult classics didn't gain any meaningful popularity on release.
