Did you just see a certain YT e-celebs video about FF1 by any chance? Your timing is suspicious.
>Is 1 even a real Final Fantasy?
What kind of a question is that?
Yes, it is. It spawned the saga, and saved Square from going bankrupt. It's however late-80s NES game, so don't expect it to be mind blowing cinematic experience. Nor an easy game.
That being said, as an fairly old fan who's played all the numbered + many of the spinoff FF games, I'd say that the NES originals (1-3) can be skipped without losing anything.
IV, VI, VII and IX are the most beloved games by the most fans, and the ones I could easily recommend to anyone.
Out of those, I'd say 7 is a safe bet for a beginner. It was a huge phenomenon back in the days, and it's still very enjoyable, atmospheric and even comfy game. The gameplay-mechanisms are simple enough for rookies, but hard enough to master, soo it keeps even experienced players interested. There's also tons of optional side quests, minigames, etc.
After that, choose your poison. Since the stories and worlds are (usually) not connected in any way, you can pretty much shoot blind. Different things appeal to different people, and that's also why there's so much arguments about various titles in the series.
I for example really liked the FF XIII trilogy as a whole, but I know that many bash it as the worst blunder of the millennium and death of the series.
The ones I would personally recommend skipping are the NES originals (1-3) and the MMOs (11 & 14). I also wasn't too fond of VIII and XII.

enjoy your loading screen hell.
The GBA and PSP ports are more or less based on that, and play much faster.
