Thanks for the comments, guys. I'm very happy that it seems to work.
@ nutnut
Do you have frozen animations checked? I had the same problem when I first added the unit until I unchecked that option.
@ lymond
1) Thanks, I'll add that in.
2) I have created the mod with the intention of having a loosely historical base. That being the case, soon after the the Normans attacked England, the Welsh began attacks on the western part of William's new empire.
3) See above. The Welsh didn't necessarily attack the English, but rather the new Norman occupiers.
4) I'm trying to think of a victory option for the Normans that involves them successfully conquering and ruling the Anglo-Saxons. I want to make it so that taking England is not too difficult, but holding it is the real challenge. (I will add checks to the code so that if the human is playing as England they don't get screwed over and still keep a different victory condition for other civs.) The timeframe is still up in the air; I've thought as short as the Domesday book or as long as the Magna Carta. Atm its somewhere in between.
5) Thanks for the reminder. I'm pretty sure Ekmek's lh guide has something on fixing this; I'll look into it. Its just difficult when its not happening to me.
6/7) The balancing is something that has not been worked on very much. I don't have time (nor quite the machine power) to spend much time on this. The thing about adding techs is that there weren't many advances in those days. I'm planning on expanding the unit line, so that should help, but I'm always looking for things to add. I believe Epic/Noble are the settings that I choose when I load it up.
8) I'd rather not have to turn Espionage all the way off because it screws with the culture system something awful. I will look into editing Espionage to make it more appropriate though.
9) I'm sure I will be able to find another use for GP somewhere; I'm looking to add new components to the mod (which will push the limits of my Python abilities) one of which includes using a Papal Favor system. I know the Charlemagne scenario has something like what I want, but it seems a bit broken to me. (I.e. its too easy to gain favor). Maybe you can use GP to gain favor from the Pope (again probably part of the Norman victory condition). Really this depends on what features I make.
10) I'm not sure on this, but from what I gather the concept of open borders is not exactly a medieval one. If this is too restrictive to gameplay I can move it back.
Thank you for all of the great feedback- it really helps to have someone who understands balancing this game better than I. (I guess modding more than playing really hurts my abilities in that field.) I'm just really stoked that the mod isn't broken like the Warlords version.
I will start working on a new post, and I will have something up tonight, but it'll be under construction over the next few days.
EDIT: I've taken care of the fish, and I hope Harold looks better. I am going to upload right now and get ready for the new thread.
