The truncated dialogue choices you see in Fallout 4 can be improved with this neat mod.
Full Dialogue Interface, is a new Fallout 4 mod that makes the game’s dialogue interface feel more like Bethesda’s precious games, and less like Mass Effect. The mod is actually an English translation of Shadwar’s Russian NewDialog mod, by Cirosan.
Not everyone likes the way Fallout 4 shows you dialogue options, which are truncated, paraphrased versions of what your character’s going to say. Often, the thing you think you’re saying turns out to be something else.
The mod changes the button prompts to numbered lists, and shows full responses.
Here are a couple of screen to illustrate. You can download it from here.
