humm these are a good ideas. I could even have certain abilities that are only available if your stats are high enough. Laziness could sleep in any bed and it could heal you. Obesity could let you eat raw food without cooking. Materialistic could multiply resource chances. Apathy could effect mission awards. Neediness could allow more companions or have them heal you after battle. Recklessness could spread your unluckiness to everyone.
Thanks for the comments! This could go deeper then I imagined.
