At the end of the day the new Pokemon games are a great idea. I've seen so many people talk about how their girlfriends are super interested in this, especially due to co-op.
I've seen people who don't like Pokemon wanting to give this a shot elsewhere and it makes sense why.
As much as there are Pokemon fans, there are still tons of people who aren't, and this game will be the perfect bridge for a new generation of Pokemon fans.
Pokemon enthusiasts need to realize that Pokemon as it is in its current form is a lot to absorb for a newcomer with IVs, EVs, Breeding, Natures, Abilities, Physical, Special, Held items, Pokemon count...like it doesn't seem much to people who play the games often but you step into the series new and it's a lot to absorb all at once which can be daunting, especially the breeding aspect.
This is good for the series to have a focused title that is easier to grasp.
