How about depth? Books, dialogue, politics and such?
I can answer that one, there similar to Oblivion. Some books have more pages to read then others. Some have 5 pages some are just 2 pages and some even have 14 pages to read in one book. There are new ones as well, journals to be found on characters, notes to locations and there are notes on bounty jobs available. I won't say to much on that.
As far as dialogue and politics is similar to FalloutNV as far as opening up options with perks such as a high speech will open up (persuade) etc. Politics not sure what you mean, not a strong area for me. You mean like Factions having wars or one hates the other etc.. this is in there.
