Wow, this is hard.
Identity is amzing in the story, and I love the use of FR tiles.
Kyanite is one of my favorite hacks. I love the tiles, and Mapping, and a very fun and interesting story! But, as SwiftSign said, I'm pretty sure the screenies are out of date. Kyanite has had a restart, with alot changed.
FloraSky has some of the best tiles, and that's pretty much all I can say about it.
Well, My vote goes to Kyanite, because it's just amazing in all aspects.
I love the great mapping, becoming a GYM leader, and the amazing new tiles. :3
