Wow, I'm surprised at how many people say they will take it slow and not rush through. I always did just about everything before I hit the Elite Four. I always fought every trainer. Also, I find it strange to hear people say they will build a team they like, over what's good. I always just picked the pkmn I liked best, good or not. Granted, I usually made them good by the time I picked a move set and put a team together, but still.
Scizor has ALWAYS been my #1 favorite. I loved Scyther back in Red/Blue version, and when I first heard that it was getting a Steel type evolution in Gold/Silver, I just about snapped. Ever since, Scizor has been my #1 favorite.
However, I plan to trade over my own 'starter'. You know, play the game with a pkmn other than Chimchar/Turtwig/Piplup. I was thinking of picking Dratini... I will pick Chimchar this time, seeing as how I picked Piplup last time. I will eventually make Plat my main game, and transfer my teams and legendaries over to Plat. I love my team with a passion and refuse to let them go, even with a new version on the horizon. I'll save them until I beat the E4 then pull them over onto Plat.
