Okay, let's start with PT (Pokémon Trivia) then, as you already found it earlier. It's part of the Wide World of Pokémon, right here. It's a place that mainly consists of various relaxing Pokémon related forum games. I just recommend to check out a few of them and see which you like. There are also a few special games that are worth mentioning:
- Watch out for Ghosts (the one with the Chit-Chat tag) - it's basically a chat that can be about anything, as long as it's Pokémon related. Another thing is that you count in each post and when you reach 100, 200 or 300 you become a ghost! As a ghost you may shout "Boo!" to make the count start over again. You also get a special emblem (which can be seen under the "Emblems" tab on your profile, as a special badge.)
- Choice Quest - Since you found this one already, I don't think I need to explain much anymore. ;)
- Who's That Pokémon? - A weekly puzzle hosted by the moderator Meadow a small piece of a Pokémon's dream world art is heavily enlarged and people can guess which Pokémon it is. You can win some cool emblems here as well.
