>>32786328The random locked doors at the power plant, the ghost girl, those random letters in lumiose, the train station that led to nowhere, the "chamber of emptiness", the sun dial, zygarde as a whole, etc. I could go on and on honestly, there were so many things that were shrouded in mystery that I was expecting to be fleshed out in a third version or sequel that never came to be.
Don't get me wrong though, I love the games. I love the atmosphere of Kalos, and the sheer amount of wild pokemon is amazing. Y version is probably my most played through pokemon game of all time, just because every time I play through it feels different. I was just really hyped for a deluxe version ala platinum and am disappointed that they didn't make one, it honestly would have been one of my favorite games in the series.
