📋 About This Mod
This mod is no longer maintained on the Nexus. Please visit the Wiki or Twitter for details about the latest version!
DESCRIPTION
This mod is an expanded offshoot of my Tell Dad About Jonas mod and adds some additional dialogue options, mostly during the character generation phase in Vault 101. It also includes the option to tell Dad about Jonas, so you can replace the earlier mod with this one if you want. The options added here are intended to address my personal shortcomings with the game and I may add more in the future if I find any other opportunities that I feel were missed. All new dialogue options are fully-voiced using clips from existing dialogue.

INSTALLATION
Extract all the files in the archive to your Fallout 3 data folder (which is the same folder where Fallout3.esm is located) and then enable the ESP either in your mod manager of choice, or under "Data Files" in the launcher that runs when you start up the game.
D.E.R.P. adds extra dialogue options to the base game, filling gaps the author felt were missing. With 362 endorsements and over 10,000 downloads, it's a modestly popular choice for role-players seeking more conversational depth, though it hasn't been updated since February 2021.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 362 endorsements and 10,720 downloads—clearly fills a need for many players.
- Lightweight and focused: just adds dialogue options, no bloat or extra systems to manage.
- Perfect for role-players who want more ways to respond in conversations.
⚠️ Cons
- Last updated in February 2021—may be out of sync with the latest game patches, so compatibility is a gamble.
- Dialogue additions are subjective—what the author felt was missing might not match your expectations.
For role-players who crave more dialogue choices and feel the base game's conversations are too limited. If you're a completionist who wants to exhaust every conversation path, this adds variety. Skip if you're fine with vanilla dialogue or want gameplay changes—this is purely conversational.
💡 Beginner Tips
- Since the mod is from 2021, check if your game version is compatible—if you're on a newer patch, test it early to avoid mid-playthrough issues.
- If you use a mod manager, install it through that to keep track of it easily and uninstall if needed.
- Look for any patches or compatibility notes on the mod page before installing, as the description is sparse.
