I'm worried this sort of takes away from the idea of character skill being important, more important than player skill even.
Totally valid concern. A few things to know about this:
- Paying close attention is important sometimes, but for a lot of our "optimal"-feeling options, a skill check will also be involved. So good for you figuring out that some character is susceptible to flattery, but if your Resolve is too low, you won't be able to flatter in a way that doesn't seem hollow.
- It's often not the kind of logic that would require a high perception - just common sense in many cases. If you take the Perception option to tell the currier that no woman would ever lay with someone who smells as bad as he does, yeah he probably won't be as forthcoming with you. So maybe you want to think twice about choosing it in the first place even though it says [Perception] in front of it. Looking for some level of thought, not necessarily brilliant levels of deduction. Anything that requires a brilliant deduction will generally be gated behind an appropriate skill check.
- I would urge any player to really roleplay his or her character. It's not something I can enforce on my end so much as encourage, but I would want players to choose options based on how they think and what they would say. There are a number of other systems choices we've made here (personality rep and background come to mind, as well as our companion interactions) to try to help the player to develop a character over the course of the story rather than to just play some empty, static avatar. Hopefully it gives a little more meaning to the overall experience.
- I have to be careful with my use of "optimal" in reference to quest outcomes. What I generally mean is an outcome that avoids conflict, not necessarily the outcome with the most favorable end result. The idea being, if you're going to skip a fight, we want it to feel like it's a reward for both player and character ingenuity. Otherwise you've just missed out on gameplay. (Which I'll grant you some people prefer.)
All that said, if you find that some interaction really forces you to metagame to get the option you want, and requires you to act out-of-character, that's a serious narrative issue, so go ahead and report that as a bug.
