This is another one of those "the gaming press is always evil and corrupt" bits, right?
Is it? No, that's hardly fair. It's a healthy dash of salt used when a developer is explaining a new feature to an upcoming game, how it's better than before, an improvement and so on and so forth. As is expected of them, they're selling a product. Look, our new and improved journal of awesomeness.
Great that you agree with the hype, but spare me describing it as factual statement from the developer.
If you think the dialogue is a problem, why do you want the dialogue approach taken with the journal?
That would be because I don't see the dialogue as a problem. I'm fine with the limitations of it as I am fine with the journal in BG1, in fact I'm really impressed with it.
I like it when that dialogue sounds like real dialogue, so I'm willing to pay that cost.
I like it when that journal sounds like a real journal, so I'm willing to pay that cost. Except that's not fair, to me it's not cost, it's a limitation of the cRPG.
When I do something bad in BG1, the journal is more sarcastic and when I do something kind, it's more kind. A perfect 1:1 for my character? Nope, but neither is the dialogue.
The tone of the journal is very neutral, never dripping with sarcasm or any emotion. It is something that could be a functional journal for just about anyone, but you're stuck on the least interesting thing about it.
The most interesting thing about it is how it is used to bypass the limitations of the narrative of BG1, which is very much technical, due to low-res graphics, little dialogue and sometimes difficult to follow plot. The journal tells the story. It explains quests, it does not give you bulletpoints. It treats you as a being with brain-capacity, it does not dole out quest-markers.
So in the end, the journal in BG1 brings the game far closer to the actual AD&D session that BG1 was based on. That's the great thing about it, not how it "sounds", which is very nitpicky.
The BG1 journal made for a great tool and gave the story much needed character and depth. Sorry if you couldn't deal with the tone of it.
