The game have so much detail to it, and soooo many gaming- and expansion packs. I have explored some secret worlds and even tho I have played 1400+ hours, there is always new things to explore. I'm amazed.
The Sims 5 is actually coming, and that is fun :D Don't know when, but I guess this is maybe the death of the expansion- and gaming packs of the Sims 4.
