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.
Yeah I agree, the only one of these gimmicks that has been somewhat good is mega evolutions and they are still not great from a balance standpoint. Other than that I struggle to see how fundamentally different modern Pokémon games are from the old ones. There’s a lot of QoL stuff, but most of it is easily ignorable imo.
I think that you might want to look at rom-hacks like someone else suggested. You’ll probably find what you’re looking for in one of the hundreds that have been made.
