When I first learned about the games, I wanted to get Pokemon White so I gotten that because of pokemon like Reuniclus and Lilligant! But yeah it didn't matter cause Petili and Cottenee were both obtainable from an in-game trade, so no matter. Still though, Reshiram was amazing, so was Braviary and Iris!
But still, on the sequel, I wanted to try out Black and it's exclusives, so, I bought Pokemon Black 2 as opposed to White 2, to try out Gothitelle and Mandibuzz, but there was so much of a great variety of pokemon like Growlithe and Trapinch so I couldn't say no. ;___;
