The same with MMOs. If a financially supportive group is still logging in and playing after a few years, the game is of good quality. If, after a year, no one is logging in, the game isn't of good quality. If it were, more people would be on.
It is relative (since quality to the individual is based on opinion) but you're right as well.
I was just making it clear to the person I was responding to that not everyone finds the updates lacking in quality.
