i still think Sapphire is my fave out of the ones i have owned, which include yellow, gold, and silver.
on sapphire i have Jirachi and Mewtwo, which makes it all the better.
sapphire, to me, seemed like it had more secrets in the game, which left a lot more to do. anyway, the whole series itself was revamped by Ru/Sa. I mean, silver was great, and i do mean great, but to me sapphire kicks it out of first. on silver, i have near 250, close, but not all. On sapphire, omg, i love the 80+ new addition to the game, espeicially Metagross? forget squirtle, charmaner, bulba, and cyndaquil (man ive played this series for far too long), just , to me, almost every new aspect of Sa/Ru just.. makes it that much funner to play.
