Pros
The leads have good artistic vision and are very accomodating and friendly. Ed Boon, the game director, was one of the original creators of Mortal Kombat, so he has a strong vision and passion to create a game that he loves. No sabotaging of the studio to chase a quick buck through forced live-service projects or sacrifice of integrity as far as I can tell.
Cons
NetherRealm is owned by Warner Bros, which puts lots of ugly corporitization into the mix. Employees aren't allowed to have unapproved creative endeavors outside of work.
