Caldera.py produces maps that not so much look, but very much play like the history of the Mediterranean Sea. It aims to be the perfect cross between a land map script like Pangea and a water map script like Archipelago by making water units optional rather than superfluous (on land maps) or obligatory (on water maps). Replay Mediterranean history: As the Romans, conquer the Carthaginians' rich islands and face Hannibal's army coming over the Alps. As the Greeks, piss off the mighty Persians, then block their huge land army with a handful of phalanxes in a narrow choke, while your triremes dismantle their fleet. As the Ottomans, use your frigates to gain command of the sea, preventing your opponents' islands from reinforcing their motherland, then bombard their coastal cities for your cavalry to take. You can even use the Vikings as stand-ins for the mysterious "Peoples of the Sea". Or you can simply "go Lib", build 50 cuirassiers and conquer the mainland for a domination win. Get it here! About version 1.0: The script isn't quite where I intended to take it, but it's been collecting dust on my hard drive for so long already that I fear I may never truly complete it. So now I'm releasing it without those few extra features I had in mind. Bug reports and any other type of feedback (even negative) are welcome. Works with Vanilla, Warlords and BtS, if its prerequisites (map scripts: Oasis, Boreal, Arboria, Rainforest, Great_Plains and Inland_Sea) are met. About version 1.1: Fixed resource balancing. About version 1.2: Fixed a bug related to river creation. About version 1.3: Changed starting plot assignment to be more reliable and scale better. About version 1.4: Added a new option which allows civs to start anywhere BUT on the mainland.
