first of all: mods. the elder scrolls games have always had amazingly talented and active modders that make the base game seem like an 8-bit atari relic in comparison to the personally modded brilliance before you.
second of all: more than the sum of its parts. skyrim is definitely a "jack of all trades" kind of game. it does everything with fairly mediocre quality (except for graphics), but the freedom to do all those things, and the lack of any real structure allow you to craft your own stories and individual experiences greater than most sandbox-style games would. the shitty characters and story are there to encourage you to run off where you please and make your own out of pure gameplay shenanigans, and it works surprisingly well. not as well as morrowind or even oblivion, but it has its own strengths.
