why is it called final fantasy when they keep making new ones though

this is not a post about final fantasy in general, this is very specifically a compilation post of ff7 fmvs i have recently enjoyed(?) as a guy who has never played a single second of any final fantasy in my life (although my question still stands). i have read about a million words of ff7 yaoi though! all over a couple weeks back in october! i don't know what came over me either. and then i watched advent children and understood nothing <3 i don't know who half the cast is and i couldn't tell you anything about the plot except for the parts that involve cloud getting impaled by huge swords, but one thing about me is that i love elite military academies and superpowers and fucked up enemies and people dying when killed and people not dying when killed and DOOM. so i will now proceed to make bold assertions about ship dynamics in a canon i don't actually know while reviewing another set of moving images.
