Wow, people really like Hoenn on here. It was pretty good, I guess. I like all of the regions pretty much equally, although Johto didn't quite... click with me. I can't explain it, but it just didn't feel as interesting as the other ones. Since I have to actually pick on, I settled upon Unova because I'm quite fond of its various cities, although if I had to pick a favourite city I'd say Sunygrove in Shinnoh was the best... if that was the right name.
