From Bulbapedia, the community-driven Pokémon encyclopedia.
Did you know that Pokemon games released on Sega consoles?! See Sega Pico/Advanced Pico Beena for more info.
There was also a handheld made exclusively for Pokemon spin-off games! See Pokemon mini.
My first Pokemon game was Pokémon Mystery Dungeon: Gates to Infinity, and my first main-series game was Pokémon Omega Ruby.
