I thought your username was Smogon at first. Man I am blind. >__>; Anyways, pleasure to meet you, Sam!
HeartGold's an awesome game to start with. :3 I really enjoyed it despite some of the minor things that bugged me, like the slow animations and PC box. Didn't think a remake could do G/S/C justice but boy was I wrong. It's definitely worth it to catch up with some of the newer games soon too though, like the amazing fifth generation series. Those games changed Pokemon a lot, especially visually... animated battle sprites are the bomb, haha. Make sure to play through 'em and I'd love to hear what you think about those games, so leave a message on my profile anytime! Always around to discuss Pokemon with other fellow fans~
But yesss, the sixth generation just looks so breathtaking. Pokemon will be totally revolutionized with the release of that, or so I feel. Which starter do you like? Are you as excited to see their evolutions as I am? :D You should drop by the X & Y board and speculate with other fans, that's always fun. Plus it's always interesting to discuss the new news as it comes out, right?
Anyway, great meeting you! I'm around if you ever need help, so leave a message anytime~!
