I have rarely come across as well thought out roleplaying settings as this, and I am definitely loving the chance to play more "Sandbox" styled games, giving the players an opportunity to affect the world on a larger scale than they might have imagined in some of the more traditional games. In Spears of Dawn there's a lot of adventure to be had and a great deal of promise.
What's more important is that the potential is not wasted, the setting delivers excitement, the options left in how the world is developing mean no two games are likely to be the same, and a campaign leaves even experienced gamemaster taking a player's seat unaware of what the other gamemaster might spring out on them with the richness of possibilities inherent in the book.
I purchased my copies of Stars Without Number before and I had a friend recomment Spears of Dawn to me, and I was happy to purchase it as soon as it came to my knowledge the book was out. My friend apparently acquired a beta copy of the book and spread his excitement to me too before the final version was out.
Sine Nomine is creating fantastic games. Personally, I've invested in Spears of Dawn, Other Dust, and Stars without Number. I'm looking forward to seeing what else they can bring, and I am excited for the possibilities in the system they use.
