Hey ya there Yammick! Welcome to PC.
I've been a fan of Pokemon for a long time too. I started with Pokemon Red and I got got addicted to the games so quickly. As of today, I'm 21 (meaning it's my birthday) and I still love and play Pokemon. I've played every game you have except Pearl and Souldsilver. I got HeartGold instead. Are you planning to get more games soon? If so you should try the first 2 generation games , RSE and then Black and White , and Black 2 and White 2. I've played at least one game in each generation and have Red, Yellow, Gold, Sapphire, Emerald (2 copies) FireRed, Leaf Green, Diamond, Platinum, HeartGold, White, Black 2 and White 2. And a lot of spin offs too. Currently there's also Pokemon X and Y in the making. Are you excited for those too? I am myself cause they look like they will be spectacular so far. All the Pokemon introduced so far are really cool and cute imo and what's neat is you can customize your trainer now. I'm so excited to finally be able to do that! Been waiting years too.
I recommend the threads Hikari10 linked up to in her post. Specifically Fourth Generation Gaming cause it seems you've played the most games from 4th gen. We also have many other non-Pokemon threads too and I think you should check those out as well. Whatever peaks your interest, you can probably find it.
Hope you have fun here and be sure to drop by my profile and chat with me if you like. Don't forget to wish me a happy birthday too. If you have any question contact a moderator and they can help you out. See you later and hope to see you around and active. :)
