In all honesty I think
Lysander would be a better representative of Sparta than Leonidas. While Leonidas is a cool leader I don't really think he actually achieved much (from a role of leadership) other than interrupting the movement of Persian soldiers and allowing the Greeks to organized a defense. On the other hand Lysander had a more effective role as the leader of the Spartans and lead them to victory over their Athenian allies. Having said that, the models would probably look the same anyway so it isn't such a big deal. Having a modern Greek leader would be cool too, but I consider the civ in BtS to be more of an ancient Greek incarnation rather than including the modern era as well, plus that LH does actually look like it might be difficult to create, even though it may not seem that way.
I think ultimately we are going to have something to the effect of Alexander, Pericles, Leonidas/Lysander, and then a Phyrrus/Cleisthenes/Solon/Milthiades or something like that rather than a modern leader. I could look into it but the more I add the longer everything else takes and I'm starting to get impatient with waiting to do the mod itself. I might actually do the mod before finishing this next module pack because I am going to have to wait on a few other people to finish it.
There are a few reasons for this. The first one is, despite my best efforts I can't seem to get the damn Assyrian units to work. Mechaerik has agreed to help me on this so once I get them to him hopefully he can fix that up. Another is the problem with the damn Filipino units, they are not coming out well at all or to my liking in any sense of the word. So basically what I am going to have to do is one of two things; the first is replace them with another civ like Polynesia. Or I can wait until I can get this stuff together and do the mod first. Since I am making a regular and a deluxe edition I'd do the regular one first since its the same as the deluxe just with less civs and rather than simply add Iroquois and Israel, I can also add Polynesia and then replace them with someone else when I release Module Pack III which will be available (hopefully) between the releases of the two versions of the mod.
And regarding Ptolemy; I have a new plan for him, so the old Alex is fair game now. Also, for Ptolemy do you think he'd look better with or without a Pharonic head-dress? Otherwise I'd give him a crown similar to the Alex LH I posted above or I'd give him laurels. The rest of his attire I already have planned out and I think it will look really cool.
