I'd say its about adventuring. So yes, a good focus on exploration, and I'd like to try RPing non-combat threats like storms. Still expect alot of combat though as this is a hostile world. There will be non-combat stuff to do. I mean someone needs to figure out the treasure map.

Covered stuff like haki in the interest thread, which was basically, yes, but you should work towards them not start with them. Haki is a high level technique after all. Technology would be listed under weapons, and will grant it as much freedom as devil fruits. You want to be a cyborg with a ham cannon, go for it.

Merfolk, I'm iffy on even allowing as PCs. Though if you REALLY want to, when you get down to it they are basically fish mobel zoan users, just always in hybrid and able to swim.
