Returned to this, and been having a great old time. Just utterly blanking all settlement building and have gotten back to having fun.
Last night I ended up some mad place with about 30 ghouls, and some raiders, ended up a three way brawl between us all, which coincided with me realising I had an "exploding shotgun", which is a shotgun which causes every shall to explode upon impact. Utter carnage with bits of ghoul littering the screen.
Tonight I finally visited the Museum of Witchcraft. Shitting myself, fully aware of what was waiting for me upstairs. Have to laugh at the folk on FB who gloat about "one shotting" it though, as they must be playing it on easy, as I sconed it full pelt in the puss, with a Fat Man, and barely took a quarter of its health.
