Which is reducing the complexity of control schemes to either nothing or mortal kombat like combos.
Forward, down, forward, high punch to build a new city in a 4X in a few years?
Hmmm I don't know. I did play Elden Ring & Clair Obscur with a controller but I also played Baldur's Gate 3 on mouse and keyboard. I also play VR games with controllers or hand tracking. Basically I play with whatever the game recommends.
To me it's like saying PC game is dead because mobile phone is so popular. Sure a LOT of players, and thus money, goes into mobile gaming but that doesn't prevent proper AAA and indies games on PC to have interesting mechanics.
PS: if you are into these kind of things checkout exotic controllers in events like Amaze. I remember a collaborative where you had to blow in pipes to push a rocket in the right direction and plenty of weirder stuff. Really cool but totally niche.
I play soulsbornes on consoles with a controller, of course. Because From doesn't know how to do any other control scheme, they have "console DNA".
But how do you play Civilization (<= 5, the good ones) with a controller?
