Luckily I did understand that having more than one move per type was not that useful, even when playing Blue as an eight-year-old. I recently found my old Blue game and my team had pretty diverse movesets (for as far as that was possible in Gen I).
My Blastoise, for example, had Surf, Earthquake, Blizzard and Hyper Beam.
I remember my Blastoise in the original Red back in the day. Surf, Hydro Pump, Ice Beam and Fissure. And he was the only one of my Pokemon I bothered to level up. And I'm pretty sure I used the Master Ball on a Ponyta.
Samurai Goroh for Smash Bros. 4! -Dreams Crushed- Well, hopefully Mewtwo and Wolf will at least be back...
