I have only done one playthrough of Fallout New Vegas and it was with very few mods because I wanted to experience it without heavy changes.
I liked the game and decided to wait a bit until more mods were released for a second playthrough. I see that there is the Project Nevada mod that adds a lot of FWE features such as FPS grenade hotkeys, bullet time, etc...
But IMO the biggest weakness of FNV was that the damage was not balanced. What is the best mod out there for damage/weapon balancing similar to that of FWE? I'm not looking for one-shot kills but I don't want vanilla damage either - something in the middle would be nice.
Thanks in advance
Project nevada is the FWE team but what they currently have releases so far is not an overhaul. Its great though.
Arwen's tweaks are the closest to a pure FWE hardcoe experience. I would use WME with Arwen's and not WMX because the author of WME has made a compatibility patch for Arwen.
Arwen's tweaks are not compatible with many other mods however so if you are looking to be able to add lots of other stuff I would go with XFO. Currently I run some XFO changes like harder AI and slower leveling along with mods like FOOK and WME and IWS on hardcoe/difficult game settings. It works well and can be challenging.
Prjoect Nevada, while awesome, does not make the game more challenging-it actually makes it easier with implants and super sprint, bullet time-etc.You can turn off anything you like in the options though.
