Because quality is not the only metric. You mentioned Siralim which kinda proves my point doesn't matter how great a game is if no ones heard of it which was what i was trying to get at not that it needs to outsell pokemon. Other factors like having beaten those "better" games or just enjoying pokemons particular mix in particular.
I agree with the listed games being good games but better? That's the rub dispite years of fuckery pokemon is still easy enough to be accsessable still puts out good monster designs still can put out a good story (you may not like gen 7 8 9 gameplay wise but all regions have fun stories in them and ill take my mandated Area Zero was just good all around)
Preferance to one game only makes it better to you.
