Here's what I'd learning towards, or maybe just wishful thinking:
1. Steampunk (Entry)
2. SNW(Mario, Donky Kong, Yoshi, Kirby)
3. Classic Monsters / Dark Universe (Castle, Swamp, Forest)
4. DreamWorks (Berk, Far Far Away, Trolls)
5. Sci-Fi (Terminator, War of the Worlds, Waterworld, Back to the Future)
6. Middle Earth(Phase 2) (Shire, Mordor, Rivendell)
7. Oz (Honorable Mention) (Munchkin Land, Emerald City, Wicked West)
