It might be, but I work on the bussines of game development, and it's very not like that most of the time. The corporations are the ones who desides what will be implemented, and you as programmer have no other option than to obey, or lose your job.
The thing is that most of those desitions are taken through social studies. Where I work the executive department extracts the data from google clicks. And the stadistics are very clear, people like something more or less acroding on the amount of clicks or the time they spent looking for such specific entry in google.
You can check yourself through google analitics and see what are the most searched words, and pages, etc...
My point is that everything we consume ist aimed to be sold thourgh emotional relation, but not any emotional relation, the emotional relation that the biggest buyers have with the product.
In terms on stadistics, the adults and group that has interest in such mechanichs in the Pokemon games don't tend to spend much money, so they will never be an interesting public to please for GF and the Pokemon company.
The little kids that asked to their parents for the game, or the casual player that is usualy a teenager that still lives on his/her parents house are the main public, the ones that invest real tangible money on the product. And, as I said before, in terms of stadistics they are the ones who would like the game.
Obviously GF has interest in long term fans, but not that much, It's bussines after all.
