You mustn't be familiar with me! I was the first modder to add Events & Decisions support for my civs, even before the mod was out (I designed some of the base E&D, too). In fact, I'm the only custom civ modder, atm, who has unique decisions
and events for every one of my - 37 - civs. Even more in fact, I tend to set the standard as to what mods are regularly supported for custom civs. So perish the thought that my civs might not be compatible
I'll write a list of things with your civilizations that don't seem to work very well with CPP and if possible I'd love for you to keep a seperate download for CPP-friendly versons of those
(bit much to ask I know, but I'm unreasonable and stuff like that)
Belgium
UU doesn't seem to be adjusted to current gatlinggun stats.
Anglo-Saxon
2 happiness on a UB with additional effects seems pretty much now, 1 would be more fitting.
If I understand the UA correctly(and I make no claim to doing so) it seems a lot weaker in CPP because you generally have smaller numbers of happiness and unhappiness and most unhappiness is mitigatable.
Swiss
With the changes to production and the removal of percentual values the amount gained from the swiss UB feels kinda unreasonable.
Milan
UU same problem as Belgium.
Denmark
Your mods gives denmark a third Unique (longboat) which probably shouldn't be there.
Iceland
Same problem as Anglo-sax, UU gives 2 happiness which is probably too much, 1 would be better.
Scotland
UB doesn't seem to provide the science on growth from normal universities. No idea if the base game 33% science is still on it(civpedia doesn't say so) but if it is it should probably be removed aswell.
Bavaria
No idea how weak the UU should be, but 22CS instead of 30 feels like it wasn't intended.
This is only counting your civilizationpacks. Many of the civs also doesn't follow the standard 1 UU, 1 UB/UI but asking you to change that is even more unreasonable so I'm leaving that out.
