I have many memories from Pokémon, but the ones related to the first generation are very special to me.
Pokémon "Rojo" was my first Pokémon game, but disappeared mysteriously with my Game Boy Color. Actually I don't miss it so much, 'cause it had a problem to save my progress, and years later I buy a Pokémon Blue cartridge so I was happy again.
At a moment of my life, after my missed Rojo, but before to get my Blue, I had a Yellow cartridge, but I think I sold it with my GBA SP. I think I will buy it again physically and digitally, I really loved the game and Pikachu back then and I think it would be nice play it in my actual GBA SP and 3DS.
So yeah, I think I will try Pokémon Red and Yellow at the 3DS.
