I’m talking about a new game but made with old graphics and mechanics similar to Megaman 9 & 10.
I personally think such a thing could sell gangbusters and honestly go on record as one of the greatest Pokemon games ever made, especially in recent years.
An old style game would be perfect for mobile. Not too graphically intensive so battery won’t drain as fast as Pokémon Go and should run on even budget phones.
They could then keep the 3D games for consoles.
