I will not elaborate because they do not even know if this makes sense 
So today I was playing myself and came to the conclusion that the game goes too fast, (maybe this is just me)
Just a few days to build a city, Game should devour more time.
I would be for it to enter:
- Creation Time items
- Low strength objects utility
- Monsters in large quantities (wolves, bears etc.)
- a larger set of weapons
- the difficulty of producing objects
Since childhood, I play the game of Survival, but here are missing the fight for their own life
