210 Pokémon, the Sinnoh Pokédex

Marriland recently posted this great video on his YouTube channel:



This goes through all 210 Pokémon in the Platinum Sinnoh Dex and shows you where to find them. For the first bit, before he starts talking, he shows you all the Pokémon you absolutely should see during your playthrough. He then explains where they all are. If you're having trouble completing the Sinnoh Dex and accessing the rest of this game, this video is a huge help. It's pretty cool to watch even if you aren't looking for help.
