It's a shame they dropped it from AC. did an earlier version have it?
It would be good in something like Animal Crossing where you can go and visit other people's towns. Then you could experience all conditions by having a decent distribution of contacts around the world. The NPC dialog, signs, etc could be in the local language too
Would be nice to have mechanics that worked in any weather and some that only work in certain conditions. Like the various subtasks in building a house or landscaping a garden... or farming: you have to grow the right crops for your climate. Different power sources... solar in hot regions, wind or hydro elsewhere.
@it_is_coming Could you explain the story-based RTS idea a bit more? Do you mean different weather on set missions, or the option of different missions?
