How does it not?
They are a connected by 1 thing: Robert E. Howard's, Conan the Barbarian himself.
Just set in different times of his life, which was long and extremely eventfull.
He did become King of Aquilonia... But cant expect him to come running when a lowby mob is wupping your arse.
And i'm sure he will play quest driven roles in the end-game parts, and that you will need to aid him in one way or another.
To be quite honest Conan/Hyboria Which is a perfect setting for a MMORPG.
At least for older pre-computer RPGer's
This has nothing to do with how good the movies(there was more then one) where, tho personally for their time i thought they where quite good for the fantasy scene they depicted.
Which is historicly a very difficult genre to capture on film befor the computer age.
It's higly dependent on how old you where and when you first saw the films.
Of course now-a-days they would be considered extreme poor, but you cant really make that sort of comparison.
