The problem isn't that it's open world, it's that there is zero guidance. There are no quests markers, no quest log, anything. The most you get is the ability to put markers on the map.
so what precisely is the problem? if you listen to what noc s are saying, its quite hard actually to not know where to go.
furthermore, there is not much dialogue. and its also not that you have 30 quests at the same time open.
heck, snes game havent gotten quest logs either. just use a notepad?
