Where is the * for the "roll <= threat level" explained? Or is an advertisment-star that never gets explained anywhere? 
I'm pretty happy with the system as it is. It's quick and easy and does what a random encounter system has to do. I'm only wondering whether it makes sense to dig out some of those "skill challenge encounters" proposals to use on the easy enounters instead of having just 1d4-1 to give the players a little more influence to the outcome of the encounter. Something like "If you sneak up on them you can easily overwhelm them" and losing surges based on the the results of those rolls. There should already be some idea for that on the net, although I have non at hand.
The Slaughterhouse system is awesome. I finally read it and it's a really cool and easy system for a kind of randomness on a higher level. But it won't solve the random encounter thing. But I'm going to use it soon. I really appreciate the sandbox idea. Unfortunatelly, I can't give any XP to Pbartender again.
