Ok, so I've gone through 2 complete play throughs' so far and have started a third. This third one I am cheating like hell. Started the game with X01 power armor and a nice weapon. But primarily I am working to make my settlements into huge cities.
So far only my original settlement where I originally lived is done. With a 3 story wall surrounding my little city with turret defenses on the sides and heavy machine guns on the two entrances until I can get heavy laser turrets. (Entrances are across the main bridge and the lesser path with the bridge that crosses the stream.
I have completely gutted and remodeled about half the homes (wish there was nicer looking beds and furniture) and everything has power from the 2 story building I have build that just houses the generators for my new little city.
I haven't really used any mods, just the stuff is with resources given to me by the console command.
I understand not everybody is going to enjoy doing this. But I cant be the only one who hasn't gone completely nuts in building. So feel free to post pics or just describe what you've done in game. Kinda looking forward to hearing it.
