If you need an instructions regarding HOW you will the play rather than game mechanics - is it even worth to play the game? What kind of shallow experience will it be.
I'm sorry, what do you mean?
You have quests such as
"Aureus informed you of some legionnaires he sent to the church, but could not tell you anymore".
That's pretty obvious, without telling you how to play. Go find the church, find the legionnaires, find out what they learnt.
Then you have nonsense like
"Bertia claims she lost a sheep".
Ok. So? Why is that a quest? Hell, I found a sheep, that was lost and mauled. I went to talk to her (even had the sheep carcasse with me) and there was no prompt for it? Why is that in my quest menu?
It's clearly a journal entry. Not a quest.
Similar to
"What's-her-name told you her brother Tom went to join the Fantastic Five".
Cool story. Why is it a quest? It's just a journal note. (I spoke to the recruiter dude about Tom, and he told me where he went. Why didn't my quest update? Why didn't I get a dialogue option with what's-her-name telling her where her bro is?). It's not a quest. It's just a note.
As opposed to both the Jake's Killer quest, and the "Did Esmerelda do it?" quest. Both of which update as you find information, and give you an idea of what to do.
As for "being told how to play". Well yeah, it kind of is needed, given how restricting the gameplay is. (Not a complaint about the game, just a reality). If it were up to me, I'd have gotten the information out of Esmerelda on my own grounds, a lot quicker, but I don't have that option.
I'd have asked Bertia more about her sheep, I'd have grilled the recriuter about Tom, and informed what's-her-name. That the game doesn't let you do such simple things means it does need to do a little bit of pointing, to make up for how little you can interact with the world.
And I still feel that things that are just journal updates should stay in a journal, until you uncover enough information for them to be a quest.
