Arguing about old Final Fantasies on the Internet is completely pointless, but...
I like 8. I like that its setting isn't bog-standard fantasy nonsense. I like its characters. I like that it's one of the first "modern" games in terms of scope and consistency. I like that it was localized and proofread, not just translated. I like its love story and I like its huge-ass goofy scope. The plot is dumb but it's twisty and compelling. The gameplay isn't great but if you FAQ how to get Guardian Forces and abuse status Junctions with 100-draw, you can avoid having to sit through the lengthy summons.
It's the only PSX FF I could ever, EVER imagine myself playing nowadays. For that, alone, it could be worth giving a shot.
