[color:"orange"]full descriptive text with added options based on skills.[/color]
I think the game would almost need to have descriptive text, and stat/skill based options would be nice to have. Typed questions are a pain if you don't hit the right key words, and would not work very well with a console version of the game. Choosing keywords from a list is a little imprecise (though fine for an adventure game where you are going to go through all the speech options anyway), and could counter the intended atmosphere during a moral dilemma, for example.
