Gen.V for me too,but the exact moment was when I tried out a Pokemon I hated for it's design,Milotic,and realized how autistic I was for basing my opinion on the design.
After that revelation,I went full competitive,learned pretty much everything there is about it,lost joy in the games themselves,finally lost interest for everything and stopped playing entirely.
Nowadays I just shitpost on /vp/ and occasionally hang around in the drawthread. Oddly enough,my life had gotten a lot better after I stopped playing Pokemon,but I kinda feel empty without it.
