I've managed to do it in Pokemon Yellow and Platinum. I am not too far off from doing it in W2 (have over 500, and a lot of the ones remaining are the lower evolutions of Pokemon I transferred from SoulSilver) --- When Snake sees a "!" over someone's head, he runs and hides. When the Pokemon Trainer sees a "!", he beats them up and takes their money.
Also, the thing I hated about Gen 1 and its remakes was that Oak was always in my business about finding more crappy pokemon. The other professors were way more chill. --- Vroom Vroooom! FULL AUTO!!! Kunimitsu, the goddess of 1535 posts........and counting
After that it became too much of a chore. Though I did come quite close in Platinum with about 450. --- Official Sawsbuck of the Pokemon XY boards Wheel of Time Progress: EotW, TGH, TDR, TSR, [FoH: 2%]
I did it for Red and Silver, and now I'm trying for it in Black 2. Since the first of the year I've collected at least 3 new pokemon every day. Up to around 250 now, plus the pokemon I have in my Black and White versions. If I keep going like this, I should be ready for X and Y well before October. --- GT: TwilightWolf000 PSN: SquireRamza Black 2 FC: 1206 7052 5893
