If you want to start with fallout new Vegas there’s a guide called Viva New Vegas which is split into two sections, the first being vanilla but patched (it’s a Bethesda game, so bugs are present and patched by the community) and the second being the “Extended” section which offers some QoL mods on top of the first section and offers things like better inventory management, sprint etc.

It also serves as a good base if you want any additional mods such as upgraded textures etc.

VNV also covers which mods to avoid due to the trouble they bring and it’s in a single playthrough (which can range 20-40 hours for me) I only crash 2-3 which is very good for Bethesda games.

If you’re on Linux, use this script to download MO2 into your prefix:

https://github.com/rockerbacon/modorganizer2-linux-installer/releases

(The script is slightly outdated and installs an older version of xNVSE, the easiest way to solve this is to download latest xNVSE and apply on top)

Enjoy the wasteland, courier.
