What was the first starter pokemon you picked from the first pokemon game you ever played?

treecko!

Charmander in Fire Red. I think.

It depends on what you count as a first game or picked. I had a used copy of X as my first game, and I can somewhat remember that when I started playing, all it had was a level 99 Talonflame, and the trainer was in route 2, with the game finished and many full boxes of rare Pokémon. I restarted the game many, many years later but couldn't save all of the Pokémon by trading and didn't have Bank at the time.

The first Pokémon game I really played was Pokémon Sun, because I learnt how to restart the game. I saved the important Pokémon like legendaries by trading them, of course (I still have the Solgaleo and Magearna from that save file, but I haven't found any other Pokémon and I can't remember any other Pokémon since this was back in 2016 or early 2017), and then restarted and picked Litten. I don't think Litten made it to the league as I remember that during a later playthrough (I loved restarting and replaying these games after finishing the credits), I saw completing the league with my starter for the first time was an achievement. I also remember that I usually boxed starters for the Legendary or when I reached the top of Mount Lanakila (with exceptions), so Litten was probably an Incineroar when I left it in the box.

I only started playing the video games around four and a half years ago, when Sword and Shield were new, so my first game was Sword. In Sword, I picked Grookey as my starter. I don't really have a specific reason, but I usually pick the Grass-type starter.
