The best pokemon games are most probably HG/SS, because they combine the glorious times of G/S with the improved in game mechanics of the latter games ( Higher IVs, Refined EV system, etc ). Since every pokemaniac can't deny its love of G/S/C, I think this would be a fair compromise. I still love playing the real thing, but as a breeder, it's saddening to know pokemons won't reach their statistic apex because of the IV systems. I think IVs only go up to 15 in the original G/S/C, whereas thet can reach 31 in the afterward games.
Nah, forget it, I change my vote for pokemon snap! ( Joke? Who knows...)
