I'm curious; what exactly do you mean by Morrowind's battle system and "no active quest system?"
I get the "no active quest", it has to do a bit with quest organization in the journal and as a side effect the gps system. I did like the organization level in OB but overall I preferred the MW+Tribunal journal overall. The whole MW journal set up was more along the lines of, "hey, something weird happened, let me record what might be important." I felt like the OB journal was an instruction manual for quests.
People seem to keep skipping past the repeated "extremely small odds" and "only if you're not careful" mentions.
Mind if I throw out some numbers on your behalf, everyone likes numbers.
This is based on average burglaries in an average city with average protection.
A district has 30 houses (maybe a small city, idk what tesv has in store).
30 residences -> 60+ people
about 1/5th of people would be willing to steal.
60 people -> 12 thieves
Of the thieves about a third are experienced, can pick an average lock. This would exclude most druggies and thugs, they like easy prey.
12 thieves -> 4 contenders
The district is entirely middle class and the crime rate is 1 burglary a week. 33% that an able burglar might hit 1 in 28 houses. (2 residences for the thieves)
All the sudden its close to a 1% chance that a burglar might hit in a given week, let alone take anything.
Of those 4, one is just average, one guy could go for a second story route, one could get past a trap, and the last might be experienced (braver, expert locks, traps, some second story abitiy. Probably an actual thieves guild member.)
So a 78.3% chance nothing happened, a 20.3% chance someone tried to fiddle with the lock, a 1% chance someone broke in, and a 0.3% chance a burglar was able to nick anything at all, and then it was probably light and smallish.
This is all without gaurds, better locks, better traps, paid city watches to patrol more often, connections with the thieves guild.
Note that the statistics are not real, just trying to get a general idea.
