Rhye, I'm no where near the mod maker you are (to state the obvious), however, I
do playtest games.
Any event in any game that causes widespread chaos and the self-destruction of the player
even if it was preventable is to a degree
seriously flawed.
This is (was- until you fix plague) the best mod our there for civ, bar none.
I was stunned that you increased the sickness in cities from plague before you even saw players reporting that plague worked.
Anyway, the basic rule of fixing a problem with beta testing is zero in on the issue, make a dramatic change in the opposite direction to see if the issue is (over)fixed, then proceed to ratchet up the changes to where you feel is reasonable.
Eg. you want plague to be a 60/100 in effect, you are getting 99/100. You don't make what you think is the right change to 59/100 for the simple reason that the change might only be 98/100. You make a huge change to 30/100 and see where that change REALLY brings you. Then you ratchet back that 30/100 to 45/100, then 52.5/100 and so on.
In the case of plague, plague kills units (we know there's other issues but this is the immediate game breaker). So. Stop killing units completely.
With the first semi-random plague, deal out a damage hit of 1 pt in the city that has plague, .5 to the adjacent area, .25 beyond that. Do this each turn for the length of that first plague. For the second plague double the damage to a base 2, the third plague a base 3, and so on.
One of the main things you want to do with plague is to kill old units, this will still do that. trust me if I have maceman and I'm hit with a plague that lasts 7 turns those maceman even with healing are half way dead. I'll probably still have maceman for the second plague and those maceman are probably going to start having casualties. The thing is, for those plagues, the units aren't old. The plague will likely kill any of my units near a plague center that are 3-4 strength, which in most cases will be my out of date units.
Anyway, I'm sorry if I'm coming across like I know anything, I'm just trying to give my thoughts and be productive so I can play your mod. I appreciate the mod and I missed playing it the last week while I waited for the new release... now I have to wait all over again.
