Hiya Prince_Yukio, welcome to PC!
It's great to hear you have a DSi and can finally play some more Pokemon! Hopefully some time soon you'll be able to try out X/Y and OR/AS as well, but Diamond, White, and White 2 are all amazing games, so I'm sure you'll get plenty of enjoyment out of those! If you're looking to discuss the games, check out our
main series Pokemon gaming forums. In particular, you'll probably be most interested in the
Fourth Gen and
Fifth Gen gaming sections. We even have a few events going on there, like the feature Fifth Gen music series and Adventures in Unova. Oh, and finally, you should also stop by
Pokemon Gaming Central, where we discuss anything and everything Pokemon gaming related, regardless of generation!
Hope you enjoy yourself here! If you ever have any questions, just let me or any other staff member know and we'll be happy to help out. See ya around :)
