I'm thinking Dragon Age: Origins without most of the fighting involved; a game where dialogue is its main "mechanics." Conversations and RPG's are usually related because many RPG's have dialogue and the ability to choose an option within said game dialogue, but what about an RPG that heavily emphasizes on dialogue-based decisions? A game not like Fallout where the "Speech Option" is clearly standardized and the only decision that you'll have to make is whether to press that "57% success rate" or not. Those kind of games tends to remove the importance of what you're saying. In the end, you'll only care about the percentages that tell you whether it's a "good or bad decision." A game disimilar to Mass Effect where the only dialogue-choices you'll be making are "paragon","neutral" or "renegade" and where the sentences you'll be choosing from will be short and different from the actual words Shepard will say. Anyways, something close to Origins dialogue-wise. It could also be described as "game with elaborate dialogue system." Anyone know a game like or close to this?
