It's very big and complex, and no game will EVER be the same as the last, even if you raise the exact same stats every time. I love it, but there are those who won't. Did you ever play Oblivion? Because that, despite being good, is a million times worse than Skyrim.
I'm unsure. I'd love to visit Kanto or Johto, but then again, Unova is going to be a significantly large and awesome region when B/W2 come out so yeah,Unova seems an excellent choice. it also means I can still get Eevee, Lucario and Arcanine alongside a Galvantula, Bisharp and Braviary.
