Playing Pokémon Gold on the Gameboy Color and trying to play the game at night on a car using the street lights to see the game, discovering you can go to Kanto after beating the main game, the day/night cycles, making various kinds of Pokéballs, being able to catch both Ho-oh AND Lugia, that Lapras on a cave, trying to catch a shiny Ditto for hours, etc... I could talk about this game for days, so many memories xD
Pokémon Platinum was wonderful too, played it a lot with my friends and we spent a lot of time on those secret bases, competing to see who had the best one and mining for stones.
Other than these 2 games, the other Pokémon games didn't feel as good to me, recent ones have been pretty lackluster on content imo.
