I have a couple suggestions!
- Have negative experiences be able to impact mental health. Like depression causes rest and relaxation to go down faster. Maybe with like a meter that when it reaches 0% you... sewer side. And also anxiety that when it reaches a certain percentage of anxiousness you aren't able to go to class etc.
- Be able to have people or users who, for example, use too much unwanted force experience consequences.
- Have the possibility of a 'wildcard' skill that randomly lets you view and pick choices that your level of a certain skill normally wouldn't allow.
