There are lot many things to remember and we tend to forget many.
So i have listed down some stuff that we need to keep in mind.....even if we forget others.
Expert can remember many or almost all the rules and times...but for some beginners and intermediate players things can be a little pain and hence this guide.
1. Villager Creation time = 25 seconds
Loom = 25 seconds
Hence, in 8 minutes, you should have 8*60=480
480/15 = 19, ie (18 villagers + 1 Loom)
Ideally, 20 villagers + Loom is what people achieve.
2. Comma;B;E = Build a House
3. Comma;B;F = Build a Farm
4. 10 Food, bush --------- 31 sec
10 Food, farm --------- 25 seconds
10 Food, sheep, boar -------- 20/21 sec
That means, Hunting is faster than "Foraging(Bushing) or Farming"
