Sims 4 is my favourite game in the series, splitting the large city into separate lots made this the first sims game that didn't perform like absolute poop and take years to load. The sims behaviours and unprompted interactions with one another was also an improvement over the previous game. In general it's just a much more polished and nice experience.
Hints:
#42 - Hint: The origin story of a hero who wards off darkness.
Supplementary Hint: You get quite the nasty but necessary hazing into a new organization.
Supplementary Hint 2: A threat spawns and as you progress through the game locations are destroyed.
Supplementary Hint 3: You can donate money, resources and other items to allied factions at your camp to make them stronger for the final battle
(Though it's thought that donating actually does nothing.)
#40 - Hint: It's out third trip and we're going down under!
Supplementary Hint: This series is a spin-off of another series but became more popular than the original with it's large openworld.
#39 - Hint: It... won't.... stop.... continually featured on this site.
