I've caught all the Pokemon Available in Blue Silver and Sapphire. No trading or anything like that so the Pokedex was incomplete but I couldn't do anything more without trading. Black 2, I've completed the National Dex. It took me quite some time with trading though. Now, I'm working on actually having all the Pokemon instead of a completed Dex. Next to RNG, EV training, and getting my teams ready. Honestly, Pokemon is way to much of a time consuming game.
