I have bad news.
9/10 you missed something. I used to look at my journal at the end of each chapter and go "Man, so many broken quests". Then after I finished I started googling things and...uh...most weren't broken, I either fucked em through violence or I just plain missed something.
I went through it last night before act 2. I only messed up one because I didn't talk to the item instead I lockpicked it lol.
I've played over 40 hours now and it really hasn't bothered me. This isn't a "go through check list of quests" type of RPG, so don't approach it with that mindset. The journal is just there to track important information related to the quest, not tell you what to do. I could see how it would bother the hell out of an OCD completionist, though.
I have a 119 hours. Mainly because I am a completest. I just got to Act 3 heh. I spend most of my time deciphering the quests. Older games like this the quest log at least gave you hints where to go/do and no markers.
This doesn't really give hints and half the time broken (like completed still being active) markers.
Other than some broken/bugged quests and the Journal being a pain in general to navigate, there is nothing wrong with the current system. The game isn't going to tell you what to do or where to go. That's up to you to figure out.
So this system which is worse than the old system can be looked over?
* Broken Markers, no need for them
* Except the log most of the time doesn't give clues or hints
The old ass games had no markers and the log was very useful. This isn't the same.
Luckily you can just complete most be being a pacifist first, then the aggressor. Also by exploring everything. Also keep the non common books.
I love this game, its the game of the year for me but please the quest system isn't like the old days. If it was the log would be VERY useful and there would be no markers.
