So, you are thinking about letting the player decide what the character says? If so, that might be good, if you can pull it off.
That's it, yes. A bit like a bioware game, but without the long-term effects.
Will there be consequences of any kind? If not, there's little point to a dialogue tree.
So it's more like Devil Survivor, then. In that game, the main character's every line was decided by the player, but the only one that really actually mattered was the choice on the night of the 6th day.
There would be short-term consequences, but most likely minor ones. I don't want to have someone missing out on 50,000 gold just because they said something rude to a villager in the first five minutes.
Hehehe. You never know how influential that villager might be. I understand where you're coming from though. I think you should go for it, if you have the patience to create multiple dialogues for every
Tom Dick and Harry.
sounds good. go for it!
