Game-wise, gen 3 for the usual nostalgia reasons.
Otherwise gen 7. There’s just far too many hotties to pass up and the games were solid if a bit hand-holdy.this community was made to psy-op pokemon fans into believing gen 7 is the best generation of pokemon
I’ve found that most seem to prefer the first game they beat. For me, that’s Pokemon Sword, and I do have a fondness for it. Since then I’ve been playing some older generation games. Shining Pearl was good and had some cute lolis. However, Pokemon X might be rising to the top for me. Shauna is adorable and the cutscenes and battles with her have been quite moving.
i haven’t played the main games since pokemon black and white, but i do play competitive so generation 7 and 9 have definitely been my favorites in terms of the game. Sun and moon has the dream team of lolis so I have to go with generation 7.
