The Nomads are one of the two beginner factions (the Witches are the other). And in fact, I think they are quite easy to play but also very powerful. Here are some tips - not a lot tips, but I think if you follow them you should score a lot of points.
Start with the Nomads
If you place the 3 dwellings keep this in your mind:
- one goal is: build 3 towns
- have neighbours
- in the end of the game: have all 3 towns connected
