The framework is nice but it really does feel constricting. You can only have three women in the bunker and they do nothing. No random sex scenes, no random positive events like finding stuff, healing you, training up their stats for what little its worth at this point.
They are basically there to provide limited adult content and consume supplies. It would nice if we could take the whole crew scavenging and so we can find and carry more supplies back.
This game is definitely one to watch but its looking more like its going to need a major overhaul soon.
A recent update is supposed to allow an additional spot for a companion for every completed game, but that means crafting a radio and then starting a new game from scratch, which is probably the most annoying thing about the game. We should be able to craft a bed to add space for a new companion.
It is definitely worth training with the women, because each give a bonus in one of the areas; Strength, Endurance, Intelligence.
Personally, I'd like to see threesome or orgies with the companions, but finding the videos for the different combinations may not be that easy.
