oh, man. i urge everyone to try this:
a: bump ivory back up to civ3 appearance rates.
b: make soz a small wonder.
c: play a 31 civ game on pangaea, huge map.
this is a riot. other than my initial war to kill off four of the civs who spawned in my immediate neighboring squares,
every war has consisted of ancient cavalry charges, backed up with some swordsmen and now med inf. you know a war's coming when a stack of ac appears on a border.
next game, i'm making another seven soz's for the other luxuries... and setting them never to obsolesce.
(ok, ok, i'm also going to cut the rate to 10 turns
)
oh, and i find it interesting to watch the celts use a mix of ac and gs in their apparently doomed effort to stave off the iroquois. the extra hitpoint is *definately* helping the ac stay alive a bit longer.
