In my perspective,terry wads at least take some effort to be made than''jokewads''[by that i mean,for example,a big room with only with Sm or cyberdemons or even a a map with only a long corridor to the exit.Most of them utilize zdoom features like cutscenes,the rooms before the terry trap are mostly detailed,and even the traps themself require some usage of scripting.My main point is that terrywads can not be comparable with very low effort wads,that they can be made under 1 or 2 minutes
