thanks for the suggestions, most of them are already in my mind for development.
Yes Mk3 is from a very old version with different code, the whole thing needs to be remade.
NCR wasn't descended from vault dwellers, it was descended from the small town of shady sands and the visionary leadership of Tandi who was rescued by the original Vault dweller in F1. This is doubly true if you move forward with the assertion that Vault 13 be a seperate faction, as it could be argued that at some point they would have been absorbed by the NCR.
The Pip Boy tech was actually a workaround from an earlier concept where Enc. BoS and Mutants could only found settlements on vaults, so they needed a shortcut to reveal vaults, I had some issues with python that at the time I could not resolve and so had to come up with a new plan. I would like to revive this element someday, but it will mean rewriting chunks of code back to the old concept.
As to the UU's the concept is that almost all units in every faction will be a UU, The problem at the moment is unit graphics and unique stat concepts for them. Tribe has had the most work done in this regard. For instance, Obviously the NCR should have rangers, but what exactly is unique about the ranger, what stats and promotions should they have that makes them unique to the NCR.
The Mutants and Ghouls already have unique promotions, if you view their leader traits. As to skins, that requires a graphics guy which I do not have...But yes, I intend to make a whole host of unique units. with the mutants having big heavy gun and melee weilding brutes etc. and the Ghouls having different stuff, like the glowing ones providing a medic bonus. I would also like to eventually add in extra promotions etc. that give benefits from fallout squares.
Bos will eventually have the knights and paladins, again this is a limit with graphics and the specific elements that will make the knight/paladin unique to BoS and conversely the unique elements that will go into The Enclave units. (the first steps have been laid for Power armour, with the T51b units and the advanced armour.)
The Security/Armed Security is the basic work around for having first stage troops that represent the military training available to Enclave and BoS from their pre-war heritage, again these will eventually branch off to be unique for both, BoS being the kind of Leather armour recruits you see in Tactics (the T51b unit also runs from this concept).
Yes The Raiders will have various things like this, the raiders are stuck at the moment, because of issues I have with modding the .dll and adding in the necessary modcomps I want for making the raiders work right, but they will have slave specialists(well everyone will have the option but the Raiders will gain extra benefits) The ability to pillage more resources than other factions, this will include science, food etc. through the expandedpillage mod. They will also have unique 'barbarian' units, allowing them to pillage without declaring war.
The ghouls are led by harold because he is cool! He had a tree growing out of his head! That is the definition of a cool ghoul!
Yes the Reno's will have a bevvy of gangster types, mobsters, 'made men'. They will also have unique versions of all the 'criminal' type buildings like casinoes and 'protection' that will have less negative impacts. I am also trying to work through in my head a good way of doing 'Jet'.
And I would say expand to other factions, like Vault City, Vault 13, Broken Hills, Gecko
Realistically, none of those have enough content to be a faction, they only exist for one version of the game, when I relaunch the Mk3 project, (when all the game mechanics are in) I would like to add these as special settlements that you can conquer and gain unique structures/benefits from. Gecko granting a Nuc. Power Plant, Broken Hills providing uranium, Vault City providing Specialist Medical buildings, or perhaps a unique building to do with slaves (I mean Servants...ahem!) Eventually populating the whole USA Mk3 map with all of the famous locations from the games, Vault 0 and the robotic horde, etc.
