>>38962406If the game has about 450 pokemon, I doubt kanto would have all 151 even if the 450 is split unevenly between 8 gens.
Remember, even though its genwun and a lot of kids started with LGPE, there are still lots of gen 1 pokemon nobody is going to miss. The "fan favorites" of gen 1 take up about 40 slots, so I'd say they include about 90.
