📋 About This Mod

In my personal opinion, the main quest of Fallout 3 is poorly written, a chore to play through, and severely limits your ability to role play. Thankfully the structure of the game is fairly open and mostly allows you to play without engaging with the main quest. However many of the locations locked behind the quest progression are quite cool, and it's a shame that they're more or less inaccessible without slogging through it. That's where this mod comes in.

No More Main Quest

This mod disables the main quest entirely, which massively changes the flow of the game to be a more freeform experience. With that comes added benefits like the main quest NPC's such as Doctor Li or Elder Lyons being made unessential, and a much greater potential for role-playing as you're no longer shoehorned into being a young Vault dweller searching for your pre-defined father. To further facilitate this, a simple alternate start is provided which will allow you to build your character, select from a few starting locations, and give you some basic starting gear (Do note that this only applies if you choose to start in DC, if you decide to start in the Mojave then the NV intro will play as usual, but otherwise this mod will function the same).

Alternate Routes

So how are places like The Citadel or Adams AFB handled in a scenario where there's nothing to guide you to them? The answer is that every single locked location, even the minor ones like Taft Tunnels or Olney Powerworks, are now fully accessible with no progression required. I've also slightly modified the design of some places for the sake of consistency. The method of accessing them is varied, from simple lockpicking/hacking to collecting access codes. I prefer to leave things for you to discover by playing but if you want to know exactly what this mod changes, documentation is included in the folder explaining all of it.

COMPATIBILITY:

Anything which is intertwined with the normal main quest such as Rebuild the Capital or TTW Quick Start are incompatible with this mod. Generally however most things should work without issue.
