Hey, and welcome to the forums! Another long-time fan here, though I have to say that Platinum is my favorite game (with Leaf Green having my favorite playable trainer character). It's the games that keep me with the franchise, as the other aspects of Pokemon (TV show, etc.) don't exactly interest me.
But as you now know, we do have subforums dedicated to each generation of games (though 1st and 2nd gen are in one subforum while there are separate ones for D/P/Pt and HG/SS). And be sure to check out the rest of the site as well!
And if you're feeling like chatting, leave me a message! I always enjoy chatting with fellow members!
