The difference between parsing GameState.* and PowerTaskList.*

[Entwinedime]

I would like to ask what is the difference between the information parsed from GameState.* and PowerTaskList.* since they have a lot of duplicate content. And I also found that HDT parses PoweTaskList.* to get most of the information, and only parses GameState.DebugPrintGame, GameState.DebugPrintEntityChoices, GameState.DebugPrintEntitiesChosen. So if I just parse GameState.* like hslog, will it lead to lack of information in Power.log, and if so (I think so), what kind of information will be lost?
