Yeah part of the reason that Disco Elysium isn't the "greatest RPG ever made" is that there's no objective way to rank such things and stating that as a fact seems on its face kinda absurd.

Clair Obscur is a game that almost seems like it was designed for me personally because it matches what I like about gaming so much. But mine's just one opinion, and I understand people having different ones. 😀

Claire Obscur has rpg elements, like level ups, skills and equipment.

Pretty much those elements are my definition. I feel like what you're describing with nonlinear storylines with lots of choices isn't all necessary for a game to be an RPG either. But I'm not a purist about any of it. Genres in general are approximate markers, and you can argue all you want about what belongs in what category.

If asked to describe the genre of Clair Obscur I'd say JRPG because purists have bickered enough to make me add the qualifier. But I've seen it described as RPG in lots of places, and given my thirty years plus of playing games it's very similar to other games I've seen described as RPGs.

It's kinda like "knowledge is knowing that a tomato is a fruit, wisdom is knowing not to put it in a fruit salad" to me in that if someone recommended Disco Elysium to me because it's the "greatest RPG ever made" I feel like I'd come in with completely different expectations about the game and be very disappointed.

But I'm no d&d player. I don't really like the Renaissance faire that much. When people start talking with those character voices I want to run for the hills.

Edit: Downvote all you like, dorks! Look at what you actually do for most of the game in Disco Elysium. You're walking around picking things up, looking at things, using them to solve puzzles, and having conversations with people. That is closer to a Sierra point and click adventure from the 90s gameplay wise than any of the many RPG games I've played.
