To me people who say that any pokemon past the original 151 are not real / good / bad are not proper fans. I mean Hoenn was my favorite region. Plus a few of the new pokemon are absolutely terrible but then you look at exeggcute and Electrode / Voltob.
Plus x & y is absolutely amazing and all these new regions are making the world of pokemon so much better with every release in my opinion.
Since I'm not religious at all, I'm indifferent to Arceus. Though I don't like how they decided to add the creator of pokemon half way through the series instead of the beginning.
1) All this massive new pokemons are mostly lame and don't have the charm of the old school ones. There are so many now I just can't keep track of them since they keep growing like weed. Old school ftw and I like to know every pokemon in depth but I don't feel like bothering with hundred new ones.
2) Arceus is cool but Mew, Celebi and Jirachi own my heart.
in my opinion, pokemon went downhill when the games switched over main platforms, from gameboy to DS. so i think hoenn was the last good region. when everything switched over, everything changed drastically, cards, games artwork, names, graphics, everything. its almost like another company bought out the franchise.
