I was kinda looking forward to these new enemies from the Null nodes. But that... was an incredible slow read.
For 3/4th of the chapter, all they repeat is how mysterious and alien those "creatures" are. And how unknown they seem. And how strange they act. And how foreign they appear. And again, how weird they behave... Well, at least they aren't bodysnatchers, eh? ;-) The thing is: I wouldn't know what to do with them from a storytelling perspective. Because nothing is known about them, I'm having a hard time putting them into anything. Having them "just there" to scare away the Decker on occasion is not very interesting. And on top of that - it's Matrix only. So the Nulls are content for one player only (at the most). Their design is amazingly boring (triangular-mouthed D&D Ghouls) and they don't really -do- anything worthwhile.
They remind me of those Crystal creatures storyline that never went anywhere (anyone remember those? No? Thought so), all those Fairy/Seelie creatures, the old Vampire conspiracy, or the Imps, or that Tutor Spirit (yeah, he was pretty much the same, only in the magic variety).
Well - what am I supposed to do with them?
