This is the PC saved game and mod list that I used as a set for my video. I am posting it as requested. To see the Arena in full build all you really need is Homemaker - Expanded Settlements and the DLCs. (Automatron,WW,FarHarbor.) And you will need PCPO - NPP - Power Conduits and Pylons Overhaul - No Passive Power for the arena to work properly.

(Consider this a self help file. The only reason it is here is because someone asked for it. )

EDIT: AS of 7/22/2016 I am opening this file for limited support. Why now? A: You all have been very good at leaving me alone and not requesting stuff ... much. B: The only requests I am getting are questions like "What is this, what is that. how did you build this?" etc. I am finding those questions interesting. I will open the comment section so I may share the answers with all. I might answer little things about getting it set up, but I decide what are the little things. Even I would have a hard time rebuilding from scratch for myself. Over 1000 hours of work (and play) is represented here. Anyway, stay good and I'll stay willing to tell my tales.

EDIT: 12/4/2016 I am aware that some of the mods for this save game are no longer available. I am not willing to provide copies of these mods to anyone. The original creators took them down for a reason and it is up to them to put the mods back up if they desire.
