📋 About This Mod

I've been retired from NV modding for a good two years now, but I found the time to update this mod today and finally fix the issue with the FOMOD installer.

CCO is now compatible with NMM and easier than ever to install! You don't even need FOMM any more (though you can absolutely still use it if you want to)! If you found the installation complicated before, try again - the FOMOD installer will automatically handle everything for you. Have fun! - Ciro

CCO now has a fixed FOMOD ready archive! All needed patches will be installed for you automatically - just activate the FOMOD package, pick what you want to install, and go! No extra headache!

CCO is compatible with both Project Nevada and JSawyer.

A HUGE thank you to nyrb for making the FOMOD archive! A HUGE thank you to CRS for bringing the exact issue with the FOMOD installer to my attention!

Cirosan's Classic Overhaul Release 1. 61

NVSE is required for CCO to function properly:

Welcome to Cirosan's Classic Overhaul! The goal of CCO is very simple: To make a player's choices matter by introducing a variety of new content designed to encourage careful decision-making and roleplaying. However, what makes CCO unique is that it is modular - that is to say, each file can be used independent from one another. Of course, they're all designed to be used together, but for the most part everything's up to you. Everything that CCO does is designed to make for a more interesting and fulfilling New Vegas experience.

CCO follows several design philosophies:

Choices and consequences - Core game formulas and mechanics have been altered to discourage min-maxing but still augment your character's design. Putting points into something shouldn't just marginally improve it - you'll see immediate, qualitative changes. Compatibility with other mods and old saves - CCO is designed to play nice with as many other mods as possible, and can be integrated into an existing save painlessly. Customization to suit your needs - Don't like it? Don't use it! Pick and choose what you like in CCO to customize your New Vegas experience to your liking! Quality over quantity - CCO may not be the most sizeable mod out there, but what it does, it should do uniquely and interestingly.

CCO comes with five main modules, all intended to be used with each other, but each can operate independently if you don’t like one of them. They are:

Gameplay Changes – The crux of the overhaul. Many game formulas are changed and the function of V. A. T. S. is different altogether. Classic Perks – Reintroduces man
