I dislike gen4 in general, and I didn't like D/P, but I did love Platinum oddly. Yet I still enjoy HG more, because I love Johto, my second favorite region. I like R/S/E the best, but man HG is loads of fun for me. :D But then again, even D/P wasn't BAD, because they're all good. ^_^
Yeah. But I have an extremely high metabolism so I luckily don't have to worry too much yet, but I try to limit fast foods to random treats for accomplishments, etc. :P
