Thx you mrfuji3.
It's a relief to have someone hearing me !
Indeed, the problem, for me again, is to continuously lost to a point I found it a little ridiculous ! ^^"

I agree with your proposition as with your attitude ! laugh

Concerning the child, it's (surely) a little dumb but... When I play (at least when I first play) a RPG, I really, really, really, play it with all my heart and since I'm a reaaly cheesy-sweet-heart, I'll ever do my best to be a good guy so the kids dying cause I tried to be persuasive why more like a slap in my face than a pleasant, funny and "well-written" event.

I would participate to the debat at a "higher" level.

It's just theorical but I would like to give my point of view about dialogues and roll-dice.

I completely understand it ni D&D. Because when you (as a GM) submit an encounter to your players, they choose the answer they want to give, they invent it, they create it in their mind. So the GM have to decide on the moment if the answer will work or no. And because it could be hard to decide if the choice of the players are good, the GM used roll-dice as a... referre."
It's like "I think what you said wont work but if you think so well... let's decide the dice" and the GM choose a difficulty.
This is how a imagine it.

But, in a video game it's different because the developpers have prepared everything. They have prepared the story, the encounter and the sentences. So it's not like... it's not like the game could be "surprised" by the sentence the gamers will choose. The developpers might have decided what could happen, why put this sentence or this others.
That's why they shouldn't need a roll-dice. Because they shouldn't haven't argue with the gamers.

It's like... writting a book. You will never read a book and suddenly
" - Luke, Im' your father...
Please reader, roll a dice to decide if Luke will get through it or not because I'm not really sure of what's happening next."

If as video gamers we had to wrote our OWN sentence, roll-dice would be more legitimate.
For now, it is, from my point of view, just a design decision as simple as "we will do like in a pen and paper party".
But it can't work the same since the gamers didn't create their answers and so the game doesn't have to deal with unexpected proposition.
Roll-dice is like the game is playing dumb.
Like a guy worked a lot and decided that using persuasion at this moment could change the mind of the NPC cause it would made sense. But then after he decided, well it would be logic thant this sentence works but let's just roll a dice to see if I am good at my job or not."

Again, I am not asking, here, to remote roll-dice, I'm just explaining why, from a theorical poitn of view, it doesn't seem to be appropriate for a video-game.
