Reputation would be a single stat. I don't want to complicate things too much, and if I break it down it very, very fast goes into a territory where I need to write half an AI to do the evaluation.
Right now, the idea is that selling items that help in a successful quest will get you reputation, and trophies will get you reputation. Later on, there will be some additional actions that can get you reputation. Also, reputation will drop over time, so if you stop doing things, people will start to forget about you.
