Another one "jrpgs were big during the ps2 and ps1 generally"
Uh no this never happened. You had most Square games, a couple enix games and then the rest all flopped and were unknown niches or dos with very few exceptions.
The same happened ps2xbgc years. You had some Square/squareenix games, 1 Namco outlier, and then what? Niche sellers, and doas.
Outside Japan people think ff7 opened Te door for jrpgs of all shapes and sizes, this never happened outside Square. While the numbers were different the popularity and sales ratios were similar to the genesis and snes years. Square, a couple exceptions, niches and doas.
No one was playing saga, no one was playing wild arms, no one was playing arc, no one was playing forever kingdom.
