This is simply GRM7584's Earth2.py script, with the script forcing civs to start in the Old World removed and replaced instead with the civ placement script from LiDiCesare's Tectonics.py script. As a result, starting civs will be placed either in the Eastern or Western Hemispheres. The Tectonics placement script, however, should eliminate the chance that they will start on a one or two tile island (which was a problem if you just removed the original script without any replacement.) The Tectonics placement script is also biased toward starting two civs on the same continent, reducing the danger that one civ will have free run of the New World, while the others knock their heads against each other in the East.

1.51 -- Added more descriptive text for people who use PLAY NOW.
Version 1.5
The placement script was throwing an error, so it had to be reworked. Incredibly huge thanks to Sto -- pretty much on his own, he completely re-wrote the placement code. The script is now more his than mine, to everyone's benefit!
