Nik is personally one of the top 2 DM's I've ever had from a dozen DMs. The thought and effort he put into world-building is impeccable. One of the great things I find in a DM is that the events they set up puts a sense of intrigue, mystery, and urgency, to keep the players interested so that they may come up with theories or plans on the upcoming events. If you have an NPC character associated with your PC and give Nik the freedom to do whatever, if there's a sense of mystery or something particularly unknown about them, he does something fun that connects with his world's lore. His effort includes the other PCs, so you are also intrigued by the other PCs lives and characteristics and not just the ongoing events.
