Here’s a definition of an RPG I found which seems fair enough.
“Defining RPGs is very challenging due to the range of hybrid genres that have RPG elements.
Traditional role-playing video games shared five basic elements:
The ability to improve your character over the course of the game by increasing his statistics or levels.
A menu-based combat system with several choices of skills, spells, and active powers as well as an active inventory system with wearable equipment such as armors and weapons.
A central quest that runs throughout the game as a storyline and additional (and usually optional) side quests.
The ability to interact with elements of the environment or storyline through additional abilities (e.g. lockpicking, disarming traps, communication skills, etc.)
The existence of certain character classes that define the characteristics, skills, abilities, and spells of a character (e.g. wizard, thief, warrior, etc.)”
That’s a From game whether you like it or not. Not so much the ability to interact with the environment but the depth of lore and world building more than makes up for that.
I think you’ve got a rigid image of what an RPG is in your head and you can’t see past it.
