After more than 160 hours gameplay on PC 1.2.37 the beginners tip:
- Press [ESC] and then HELP topics and read them all (settlement manual) especially about settlement happiness and power grid
- Don't build electric apparatus like TVs in settlements, scrap them if they are there cause they bug resources.
- When reaching settlement size limit, drop some guns in settlement and then [TAB] them into Settlement Workbench to lower the size limit (workaround). The size limit does not have game relevans, it is a graphical thing.
- Some places in settlements aren't actually suitable for stores, for example in Taffington Boathouse when placing wooden floor over water and trying to build settlement stores there, it is not possible to build the bar, and only the medical store actually get service.
- Play on "Very Hard" difficulty if you have FPS experience because of the legendary rewards.
- Next tip is a spoiler:
It is a roleplaying game and even if the wasteland is really really big, probably 5-7 times bigger than Fallout NV with several really really big towns, factories, highways and more, you are supposed to be a father or mother with a missing son. The game doesn't really strike you for just wandering off track, but starting on any settlement building before pursuing the kidnapped son is really not roleplaying! And it only makes it more difficult later, since settlements require supervision. It is much easier to get friendly with all the factions while finding the answer to the kidnapping and then exploring the wasteland, because then your exploration will be supported by the factions and go much quicker (the map details are enormous!) Then after all locations are exploited, start the quest and make the faction choices and start building settlements ...
