I'd like Generation 7 to be based in Oceania(AUS/NZ/Papua new guinea/Tasmania). (or just Australia and NZ)
I mean, come on we have great stuff here. like:
Spoiler:Bungle Bungles, Blue Mountains, Kakadu, Fraser Island, The Pinnacles, Uluru(red rock), Great Barrier Reef, Jewel cave, Wolfe Creek Crater, Horizontal Waterfalls, and many more. Great barrier reef would be perfect for pokemon like skrelp, barnicle, clamperl and almost any water type! seriously, check some of these out. there pretty awesome. :D
And also some great Animals to work with:
Spoiler:Bilby, Dingo, Emu, Koala, Kangaroo, platypus, kookaburra, Rainbow Lorikeet, Quoll (Spotted Tailed), Thorny Devil, Tasmanian devil, Thylacine -Tasmanian Tiger(extinct), Cuscus and many more :)
Australia would be a great place for a region. :D
It definitely would, especially with all the unique landmarks and animal species that inhabit it. There's still so many animals that a Pokemon hasn't been based on yet, and Australia can serve as an ideal inspiration for new Pokemon designs. Also, remember when we all used to think regions were only based on Japanese locations, and then 5th Gen threw a curveball at us with the American-inspired Unova, followed by 6th Gen with the French-themed Kalos.
Even if it's not specifically 7th Gen, I'd still be happy if they design a future region based on Australia. It's a great opportunity for divergent evolution of region designs.
