My Starter Pokemon was always a Fire Pokémon.
I remember that it was really tough in the FireRed and LeafGreen with the Fire Starter Pokemon,because of the first arena with Rock-type and the second arena with Water-type.Pretty much the same. It's always a hassle to catch a fire-type and having one of those does bring a lot to the table in the beginning (because you're going to meet a lot of bugs, in every game), and not much does have an effective type against fire until you're getting further into the game.
A grass-type is easily caught in the beginning and water-type isn't as useful as fire until the later gyms. Unless you really like the Water/Grass starter, it's (for almost all the games) best to go with fire.
it was even tougher in the originals since Charmander didn't learn Metal Claw since Steel-type wasn't introducedI remember that it was really tough in the FireRed and LeafGreen with the Fire Starter Pokemon,because of the first arena with Rock-type and the second arena with Water-type.
