And Queens aren't very handy to begin with, really. They only get rid of a radius of like 10 feet? I've hardly had to use them.
They're practically mandatory and you should have at least 3 on you at all times if you're going for an all survivor/quest run (which I've made all my runs be after the second playthrough, second being a zombie genocider playthrough) because of how awful the survivor AI is and how clumped zombies get at nighttime. Also, some quests almost require it to start, big example being that unannounced girl getting fucking horded in the waterway.
Also, TC these things won't be of use to you in non survivor runs but here are two hidden things they never tell you. You can only have 8 potential survivors at once loaded (psychos do not count except one) and that includes the ones in your party and in unfinished quests so you wont' get calls for new quests if your survivor count exceeds that. Here are the all the quests http://deadrising.wikia.com/wiki/Scoop . Second, you should take a picture of the outside of the safe house as well as try to get an "erotic" photo over 700 stored and locked in your camera because two quests (though you probably won't be able to do them on this run) need them.
Same goes for DR2. Even worse in that one as the NPC running the pawn shop counts towards that total. ---
