Yes, the game's genre is STILL a JRPG

Minigames, a small game made within a game.
Usually in a completely different genre to the main game.
A common concept found in videogames made over 20 years ago.

Today? They are usually known as PAID DLCs.

Or just have the game's original genre swapped OUT to a completely different genre just to satisfy the "modern audience".
