According to my "Load" files on my pc, I am pretty sure I played my first game when I was 10. I remember I LOVED Pokemon but had NO idea there is such a thing as Pokemon Game. And then a friend of mine told me he had it and that he would give it to me (on pc, emulator and stuff). I remember being super excited about it. Anyway,
My first game was Sapphire.
And I think my first Pokemon was Torchic, I was so disappointed when I saw it's evolution lol. Now I have a save file with a level 100 Swampert. (I HAD NO IDEA I BROUGHT A POKEMON TO LEVEL 100, EVER! :D )
Now I am playing Pokemon Yellow lol.
