The only ones I remember are that as a kid I had over 100 hours in firered, which I still consider one of the best games because they designed it just well enough to keep pumping hours into (Sevii Islands and VS Seeker particularly, made the endgame not tedious) I replayed Crystal a couple of years ago and got about 60 hours into that, and it's even more amazing than I thought it was as a kid Currently in hiatus on an Emerald playthrough but I'm not sure how many hours I've gotten, I think between 20-30, I'm nearing the endgame.
