Man, this board can be really frustrating. I always fail with my initial moves, but once you get out to the sea...ahhhh bliss!
It's hard to come up with a clear strategy, I like to get my hands on the smaller islands and grow from there.
For me the perfect scenario involves 6 players, 3v3 or 2v2v2.
Try it. You're gonna like it.
This is not a board for those who like to build up and hide behind high walls. You better take action or watch as armies grow around you and eventually lead to your demise.
It's refreshing to find boards that differ from the norm. I suggest you try to play it as a team game, you will love it.
