- Abandoning settlements will be a bit tricky, but could be done while adding support for capturing and reclaiming them.
- The generator in 1.3 creates islands from time to time, already. There will be at least one more major rework of the world generator in the future, but probably not until 1.5 at the earliest. In 1.3 the world is limitless, it will generate as you explore it (Minecraft style)
- One of the changes coming in 1.4 is the ability to create migrant bands from anyone, not just idlers.
- That warband behavior is currently acting as designed, but I'd like to smooth it out and give players more control warbands.
- Good suggestions for the world generator. Mountains used to be impassable, but that ran into issues with pathing (pre 1.0). With the new pathing improvements in 1.3 they're a possibility.
Thanks for the great feedback.
