Yay! I kinda want to make all three !! But for know lets focus on #1

The first one: Tribe - should it be set in a:
1. tropical island kinda place. 
2. A hot desert, with canyons, a and humid jungle area setting. 
3. A more native american forest, Savannah plains kinda Setting.
4. Other (more of a fantasy setting like a floating sky island or something.) 
5. Northern kinda place (viking kinda tribe)
