Can I make a suggestion? Maybe reverse the bars? Every game that I play I want to keep Stamina up, or Health Bar filled, same with Mana. I looked at the bechambers row and thought 'Well Tink still has loads in her bar, let's use her'. Reading your explanation I understand now what you are showing but how many people RTFM?
. Convention has us trying to keep a bar filled, maybe go with that?
I think the same instead of a fatigue bar it would be easier to have a stamina bar that decreases
In this context, the goal (in my mind) is to keep the bar empty, the idea being that excessive amounts of color in a bar indicates that you should pay attention.
The fatigue stat starts at zero, and the amount it reduces income is a squared function, i.e.
1.0 - ((fatigue_level * fatigue_level )/ 200) = income multiplier
so 5 fatigue * 5 fatigue = 25,
divide by 200 is .125,
1.0 - .125 = .875, or 87.5% income
200 was picked as 14 x 14 = 196 (almost 200), and 15 fatigue drops your income multiplier into the negatives.
Thankfully, the gal will be automatically be sent home to get rest if her fatigue stat is too high, and there's also the 'on call' system that rotates out gals with a fatigue level that is higher than the 'on call slot' threshold, if another gal is assigned to 'on call' that can replace her.
14 essentially translates to 14 days of dancing before a gal is fully worn out. Other activities require more exertion, so say playpen/orgy is 1.5 fatigue per day, or 9 days of orgies, with full exhaustion setting in on day 10...
The difficulty slider adjusts the 'fully exhausted' target with a multiplier (say 1.1) to the current base fatigue stat, fyi.
Occasionally, a gal may be in multiple battles with baddies when crime fighting, which can push her fatigue stat above 15. You may have captured a gal that you immediately had to assign to multiple days of bedrest to reduce her fatigue. I've been pondering adding a 'health' stat that tracks physical damage/degradation that takes weeks to heal, instead of days with just fatigue, the idea being that Lex may need to arrange for intensive care for a week or more if a gal has a bad run. And pushing the fatigue stat past 14 results in a 'health/hit point' of damage, but that's down the road a bit...
Anyways, that's my 'developer logic', as the goal is to keep fatigue at/near zero. There's already a lot of color going on on the management screen, so black bars helps you focus on the cute gals...
That being said, I can add a mod switch under game options that 'flips' the bar easily enough, I'll add it to the list for future updates for those that prefer a full bar instead of an empty one, but there's a bunch of other stuff on my to do list already so it'll be a bit.
