As
Dideldidum wrote it is important to get any kind of feedback for your actions ingame, otherwiese it would lead to the feeling of wasting time without any benefit for the player.
I like the idea of colored borders to show the state a character is at and/or the idea about having some text options available for the player to check the progress of each individual character.
Of course this could be implemented in different ways, especially since it seems the dev prefers some stats to be more hidden or at least not shown in a number vaule.
Just two simple examples to show what I mean:
1. coloured border:
- three possible stats per character (good / neutral / bad)
- assuming a scale of 1-100
- weighting neutral less important than the other states at both ends of the scale
example: good (green, scale from 76-100) / neutral (blue, scale from 26-75) / bad (red, scale from 1-25)
Since this is just an exmaple, the numbers of different states, used colors and ranges on the scale can of course be changed to fit the needs of the game.
2. feedback via text
- this time 5 different states (to keep it easy, just numbered from 1-5)
- assuming again a scale form 1-100
- the weighting this time is distributed evenly between each of the states
- the player gets feedback talking to the character itself or talking to somebody supervising the porgress of the character in question
example: state 1 (text 1, scale from 81-100), state 2 (text 2, scale from 61-80), state 3 (text 3, scale from 41-60), state 4 (text 4, scale from 21-40), state 5 (text 5, scale from 1-20)
Again a simple example which could be tailored to the needs of the dev for his/her game.
I watch the development of this game quite some time, because I like the idea in general and it is a seldom used setting.
Wish good luck and alot of success to the dev for this project!
