One time I did a whole run in Gold with only a Raticate, which I managed to get to level 100 by the end of the game. It was actually a lot of fun, but I have no idea what possessed me to do it since I hate both Raticate and Normal-type Pokémon, lol.
But thanks for reminding me.. I wanna do another one of these soon!
You mean like challenges? We have a forum for those. :) You can sign up and participate in some, or you can discuss them in our chit-chat thread, the CI&D! That'd be the place to discuss your playthrough of the game like this. :)
