Seattle, as I don't have to get a passport to go there. Also I just visited Seattle with my dad a couple years ago and had a good time there, whereas I haven't been to Vancouver since I was a little kid and don't even remember what it was like.
I'm not sure about the weirdest, but the Pokémon anime used to have a lot of silly puns for episode titles back in the day. One of the first that comes to mind is the DP episode "O'er the Rampardos We Watched".
Off the top of my head, a few countries that I'd like to visit someday include England, Spain, France, Germany, Switzerland, Australia, New Zealand and Japan. Although I'd also be pretty hesitant going to any non-English speaking country due to my past troubles trying to learn other languages meaning that the language barrier could prove to be an issue.
Probably Tokyo, as there's a lot there that I would want to see. Places that show up in games or anime that I'd like to see in person and companies that would be interesting to get tours of, etc.
Not really. My sense of smell isn't very strong and plants in particular are incredibly hard for me to smell. Personally, I think probably Emerald. Since Ruby and Sapphire had more emphasis on being different from each other, with different villainous teams and being the first games with version-exclusive legendary Pokémon, it felt like a much bigger deal to combine aspects of both games together for Emerald.
Normally I would say Fire or Dark, but lately I've been realizing that I like a lot of Ghost-types, so I'm going to go with that. I'm not really sure about when they were best implemented, but I feel like Gen III is when they really hit their stride for introducing a lot of good Ghost Pokémon and set the standard for what would come after that.
HEHEHEHE REVIVAL! @BZRich64 If you could change one thing about Desolate lands, what would you change?
How should I know, it just started? It's too early to tell what I would want to change. With, obviously.
