Unless they are settings that get checked fast and a lot or are for critical things like room protections, using hash is a waste of resources in my opinion. Hash is great, it is indeed very fast but shouldn't be overused. Im not speaking about any posted codes here but just in general.
I use hash tables to save information that needs to be checked often and very quickly. Simple settings that may get checked once or twice I use ini or variables, which is ini.
Also, for processing, parsing, evaluating or compiling information hash tables are great.
