Morrowind is a great game, but it has little in the ways of a reactive world, so all those pretend roleplaying concepts are fucking retarded. If a game actually reacts in some way to you doing a thing, then doing that thing is a valid playstyle. If you do a thing and it doesn't influence anything in the game at all, neither mechanically nor with flavor text, it's retarded.
You can roleplay a nudist in Morrowind because when you walk around entirely naked people tell you to put some clothes on. It is very minor reactivity, but it is reactivity.
If you dress up as a guard and patrol the streets but none of the other guards ever recognize you as one of their own, and there aren't even any criminals you can apprehend, it's retarded because you're doing something that has no effect on anything in the game whatsoever.
