So, I'm not actually sure if this have been suggested before but...
I've been thinking about what to do when out of energy to do missions and dungeons. Maybe it's just me, but standing in Haven waiting is not that fun... So I figured maybe a little free roam mode could be nice. After all, I'm pretty sure the planet is not all clockwork, there is surely a surface! Here how it could be:
-A large field with enemies in it, maybe mini-bosses in some places.
-NO DROP OR REWARDS. This is a free roam mode and adding rewards in it would cause trouble. This is just to pass time.
-MAYBE a few crowns from bosses but that's it.
The main idea is simply to pratice fighting under real conditions unlike the training area we have now. Or simply to walk around and just look. Just a little thought I had. I remind again, there would be not rewards, it's just to pass time.
It's called ATH. lol.
Surfaces would require completely new maps, and if they re-used maps, they'd have to overhaul new Backgrounds. It'd be way too much programming for very little reward, since there'd be little point to it except to "not stand in Haven".
You could always play LD/BN.
