Pokemon Red/Blue

Basically, these 2 games are just catching and fight Pokemon. It's actually pretty fun in a way. I mean like training and catching Pokemon is that best part. Or else what would the game be for? Well in case u didn't know, different version has different Pokemon. The chart below will tell u which Pokemon is not in what version (meaning u don't have a chance of getting it. e.g. u choose Charmander but u had the chance to get Squirtle or Bulbasaur):
