Hiya Bers,
could there be something like an automatic update whenever a new continent opens, maybe also with information on which climate zone it is in?
Unless I am mistaken, currently it is only possible to know by asking around. Obviously bigger alliances have a bit of a better overview due to their players being scattered over several continents and exploring there.
Personally, I don't like to play in certain climates, and I also don't like to land on a continent shortly before it is considered full. If for example a message like "A new continent X in climate zone Y just opened" appeared in CC, I could make an informed decision whether and when to start a new hero there.
