Alex has made some adjustments to his Alpine algorithm for TextMapper to get better desert terrain – e.g. Australian. Lots of generic rpg maps assume European type things – e.g. cool to cold, whereas Australia is temperature to equatorial, in general.
This is Australia as known circa 1800 – there is the colony at Port Jackson/Sydney and up the Hawkesbury River to Coal River/Newcastle.
Van Diemen’s Land also had British settlers in 1803. Unfortunately, a Ruby time travel destructive side effect put paid to that. The coastline mapped, but the continent is just a big hexcrawl at this time.
