20 years after, developers don't make these type of games anymore. That said, there is very little innovation in this game, I think they are afraid of ruin the game by releasing something completely innovative.
See, that's what happened when Blizzard has decided not to release WoW2, the addcition kicks in, and they just can't accept the fact that there will not be another WoW game and NMS isn't that type of game.
