It's the curse of the FF brand in all honesty. The more entries that come about, the more divided the fan base will become. Since every game from FFVI and onward has been radically different from the previous game, this end result is even more apparent. It isn't uncommon for a person to view something being or not being "Final Fantasy" to them based on past game experiences that they deem to be their favorite.
"I'm seeing it clearer/Hating the picture in the mirror/They claim we inferior/So why the f**k these devils fear ya?/I'm watching my nation die genocide the cause/Expect a blood bath/The aftermath is y'alls/I told ya last album, we need help cause we dying/Give us a chance, help us advance cause we trying/Ignore my whole plea, watching us in disgust/And then they beg when my guns bust/They don't give a f**k about us" 2pac ft. Outlawz- "They Don't Give a F**k About Us"
