Here is a brief opinion of some of the tribes from a member of NAO. I think this world is going to end up being won by either your tribe (NUI) or NAO. I don't think HFA, PIA, or COI will last more than 3 months from what I have seen of them. ZZZ will grab a good foothold in the North East, and D-M will hold down the South West. I haven't heard anything from either of the two tribes so I can't say much else about them. DOH looked good at the start of the world, but I haven't seen them make any real grabs for power yet so who knows how long they will last.
