Obviously it’s not hard to make notes on a paper notebook or in a text program on desktop. But it would be cool to be able to make your own notes about a character in game.
I have done this on games such as icewind dale 2 where I made actual sort of short story notes about the characters motives and background. I’m not a good writer but I enjoy it sometimes as a creative expression.
Also you can write notes about character plans in this area or observations. For example “found cave in ‘x’ area but have not entered yet”.
My observations on having something like this are: 1) probably some people would enjoy this feature 2) but they could already easily use a physical notebook or desktop text program 3) so it depends how easy it would be to code this to realize a benefit for the people who would enjoy this feature 4) it’s probably an easy idea for the developers to evaluate and make a decision one way or the other
