When comparing the two games, I'm amazed how much detail and how well they've captured the originality of the games. I was kinda put off by the XY graphics style of Hoenn since for me it might not feel like Hoenn in that style, but after seeing the E3 gameplay yesterday it looks incredible!
I have to say, those graphics look so polished! I love how the puddles retained the reflection effect they had in the originals. The trees do remind me of Sinnoh though.
