It's nice to restart, actually. You'll learn a lot more that way, though it'll take a bit of time to get you up to date on the new Pokemon. Welcome to PC, btw! You'll be able to learn more about the new generations of Pokemon, as well as get reacquainted with the generations you've lived through. You know, I'm a big fan of Generations 1, and 2. But I skipped 3 and 4, and returned to the fandom at generation 5. There's a lot to talk about for five generations. :D
If you have questions about Pokemon, whether it'd be the episodes you watched, or whatever! Some forums have simple Q&A threads where you can ask, or join the discussion! In the meantime, have a great time, as you'll have so much fun. :D Send me a message if you need any help with the forums. See ya!
