the major change concern the sea colonies, you can now build sea colonies ONLY
if there is methan in potential new city area, and ONLY in 5 tiles radius near your
cultural borders !!!
For the guys who want increase this distance, you can open the GlobalDefine,
and change the value in the last tag of the file :
<Define>
<DefineName>SEA_COLONY_MAX_DISTANCE</DefineName>
<iDefineIntVal>5</iDefineIntVal>
</Define>
change 5 by what you want, but attention !!! if you increase this value, the time
you wait between two turns will be increase!!!
