Coltrane - All the best with those applications. Academia is in a pretty bad way over here, both funding and employment-wise.

Turn times & Trade: Yes, the whole thing is much much faster now. Don't know what you mean by ctds though. What are those? I agree, trade is much more interesting now.

Philip's War Academy - Well spotted. That isn't the way it should be. Though I don't think it would ruin anyone's game. I made a schoolboy error in deleting a unit, which caused certain unit settings like that to slide a slot. I thought I'd fixed them all, but that obviously slipped through. It's corrected already over here - but go ahead and set the AP unit to Phalanx for your games before I send out the fix.

Heralds & Messengers: - Funny, I presumed scouts upgraded to explorers already in the standard game (shows how little I play it, if at all). But I see they aren't set to upgrade in the biq. I've fixed that too. Thanks.

Academies of Plato & Aristotle: - They are meant to have the same benefits. Basically, a player is presented with the opportunity to build these upon researching Education. They are then faced with the classic "hmmm, who is my preferred philosopher? Plato or Aristotle?" I'm open to hearing ways of differentiating them though.

Herodotus Unit: -

I have other touches like this up my sleeve for future versions. Idea is to bring in those story diversions Herodotus so loved. These are tied to little mini-games for the more backward civs.

Enemy Sacrifice: - Thanks for the info. I didn't know that. Have now given the enemy shield cost of 10. There's something else that needs fixing here: Both the Giapid Blood Drinker and Scordiscian Flesh Eater units of Illyria are supposed to enslave to the Enemy. For some reason the biq refuses to let me change the unit resulting from their enslave. I change it to Enemy for both those units and, when I go back to those units, it's back to doulos. Don't know why...

Heroes - No, the generic Hero is for some civs and the unique heroes are for others. They are parallel units for civs and shouldn't upgrade into one another.
stico - Glad you got it DLed! Hope you're having fun? Vuldacon has made me aware of how incapable I am with graphics. I may well have changed the palette when adding your cities in, without realising it. Sorry!! This is being fixed, don't worry. I think they look good by the way. They have a 'sprawling' feel to them, which I like. The bigger city sizes look taller of course.
