People are buying the same first person shooters, people are still playing very similar MMORPGs
Developer sell each other the same engines and they just add new textures on, essentially the same thing as another game in the series
Not all people who buy the series are idiots though, a small percentage are and they are the ones who also make the most noise because they thing their opinion is "Different, New and edgy". I call them dumb because they have good gameplay and if it's not their cup of tea then they shouldn't play it, they will just flamebait
Some people buy Final Fantasy and Halo because they are good games, it's not a question of opinion, the gameplay is good. If you don't like it then maybe the genre isn't for you or you don't like the style but people play it therefore the gameplay is good.
How many indie games have deep philosophical meanings behind them? I've played a fair few and not a single one cam close to the story of any of Final Fantasy games. Granted some indie games are a lot more fun then mainstream games
In short: people buy the games because they are good, not just because they are in the series. The get marketed more because previous games have been successful
