probably gen 4, just because of HGSS

Currently playing through SS right now, and I can see why it's so popular!

Gen 6, it has my favorite mainline game and favorite remake.

gen 3 ez the best, it keeps always a warm place in my heart

gen 4 for me, mostly diamond

Gen 7. I really liked the anime and GX cards. also that one song that plays when you fight the kahunas was really good.

gen 4 for sure :D
