The interesting thing I see according to Kubi9's summary is that because the WN doesn't contain events like Ainz saving Gazef from the Silian Theocracy, Momon being Ainz instead of Nabel, and Nfirea knowing Ainz = Momon, there's a lot less drama and chaos to be had as a result of Ainz laying waste of the Kingdom. There's a lot more emotional attachment to the Kingdom's side in the LN which makes Ainz's decision to slaughter them give a more evil impression from a basic reader POV, since you'd think a guy like Gazef would do whatever it takes to steer clear from getting in Ainz's way.

And he was also given the wooden sculpture which allows Ainz to swap with him at any time, possibly summon him period. Tons of ways it could unfold though this might just be because I haven't read the WN and only go by summaries in the wiki here.
