Another thing that Daggerfall has, which other TES games do not.
If you join a disreputable guild - Thieves Guild or Dark Brotherhood - and/or if you sink deep enough into the villain reputation and/or if you don't have a high personality - people stop talking to you. Completely! That is a terrible consequence in a game where you need to talk to people to find quest locations or to obtain work.
People know who you are, they don't like you, and they don't want anything to do with you. They already know that the last time you casually asked where someone lives, he ended up robbed or dead. You can't approach a single person, because they are shaking in fear at the sight of you. Words don't come out of their mouths, because they freeze. So simple, but so effective.
This is something which is totally missing and totally necessary in later TES games. There should be a negative consequence for the near impunity and abuse of power and privilege you get by being a high ranking assassin and thief. There is also a threshold point beyond which authorities don't care if you did your time, if you paid up for past crimes, or whatever. You commit too many serial crimes and they will kill you on sight.
