Regicide is Inferior to Mass Regicide, which gives 3 or 7 King units. My main like of MR is their use (Kings) as scouts..
I'm going to forget about CCM regicide, Moosezilla,
but NOT the CivLeaders.
Using CCM upgrade chain techniques one can add Civ leaders to the various Civs:
---create a surrogate unit that can be upgraded, similar to the "clan"
--for identification purposes this surrogate unit will be called the "regent" (not to be confused with the difficulty level going by that name)
--the "regent" unit is stats are similar to the "clan" unit since those CCM settings seem to work for speedy upgrades by the AI.
--the "regent" is set up an initial starting unit and cannot be otherwise built.
--when the game starts, under normal random game rules, there are the CCM starting units PLUS the "regent" unit.
--the "regent" unit is upgradeable to a CivLeader
--In tests, the AI will upgrade the "regent" to a CivLeader corresponding to their particular Civ in one or two turns.
Stats of the CivLeaders
The purpose of the CivLeader is to protect the newborn Civ from easy early destruction by other Civs
--defense 7 (to protect the Civ up past the ancient era)
--hitpoints +10 (further protection)
--attack 0 (to keep the AI from doing stupid things, yes I had it set to 1 and Shaka ends up moving across the map to attack a city defended by Lincoln. No more Shaka)
--flag King (no need to set defensive as it might confuse the AI, see Shaka above; prevents it from being in the building list)
--enslave (interesting possibilities of what the enslaved unit could be and what it might be upgradeable to)
--upgrades (to appropriate Civ, ie regent > Shaka> Elizabeth > Isabella > Lincoln, if you are America you upgrade to Lincoln, if England upgrade to Elizabeth.
Go into the ini file of that CivLeader and use the "figet" .wav and .flc files to the "attack1=" and "defend=" sections of the animation and sound areas. When the CivLeader is attacked, they will use these animations and sounds to defend and "slap silly" the enemy! Charles V. of Austria has a dog with him and they make quite a pair defending.
In early tests, the founding cities are often subject to barbarian attacks which are only defended by the CivLeader. This leads to enslavement and the appearance a potentially interesting unit. (in my case "sage," att4 /def1). As the defenses mature, spearmen and other units defend ahead of the CivLeader and so the chances of an uberunit appearing become much more rare.
Because of the differing leaderheads, and added / removed Civs of CCM, the CivLeader unit figure may not match the leaderhead. Oh well.
