The original 151 Pokemon of the Kanto region are found in the first iteration of the games. Pokemon Red, Blue and Green for the Gameboy – there’s some real nostalgia on these games now. The starter Pokemon are some of the most popular: Charmander, Squirtle and Bulbasaur.

You could also choose Pokemon Yellow in this set. After the anime, Pokemon Yellow is a remake of the game, where you get Pikachu as a starter.

Pokemon Stadium was also one of the first Pokemon console games. It featured party games and a 3D battle sim and spawned another popular game format.

Generation 2: Johto

Pokemon Gold and Silver released 1999 for Gameboy Color. The third game in the series, Crystal, released in 2000.

In  these games, your starters are Chikorita, Cyndaquil and Totodile. Due to being able to visit a powered up Kanto after completing the Johto region, the Pokedex runs from #001 Bulbasaur to #251 Celebi.

Pokemon X&Y on 3DS

Gen 6 marked the first games on the 3DS. Pokemon X&Y were the first games using the circle pad for non 4-directional movement. Making sparing use of the 3D slider, the games made accessibility changes to make competitive ready Pokemon easier to make.

The anime completed the letter trio of XYZ but the games never got an entry. Temporary Mega Evolutions also debuted in this region. Functionally similar Primal forms were introduced with Hoenn remakes Omega Ruby/Alpha Sapphire. National Dex: #650 Chespin to #721 Volcanion.

Z Moves in Generation 7

Ditching Megas for high power Z moves, 3DS titles Sun/Moon and sequels Ultra Sun/Ultra Moon took us to the Hawaii inspired Alola. This was the first region to introduce regional forms of older Pokemon.

Fans were finally able to try out unique battles rather than Gym Battles for story progression. The National Dex added #722 Rowlet to #809 Melmetal.
