Your bias is showing. Both events cater heavily to locals - while you may not have had bad experiences, I assure you many others have. (I had way less of an issue at HOS than HHN, but I also have been to HHN more, so the sample size is bigger.)
Real shame that ZCU15 disappoints. The clips I saw looked really tame and disappointing... not sure laser tag really works well in a mass haunt environment. Deadfall sounds neat, but I hear it's a bit scatterbrained through some reviews (including Brigante, who tends to be pretty forgiving)... any more thoughts there? Also, how's the Cursed zone?
