I've played the original US rules and FA but not DW. I like the basic mechanics but some lucky dice rolls can really effect a game (rolling 6's is fantastic in these games). This isn't a bad thing but it can lead to some amusing situations.
Thanks Onyx- yes have heard about exploding sixes. I was a bit concerned about whether the complexity of DW having Land/Sea and Air combat might make it too clunky when compared to US. I have been assured that not the case. It sounds it will be fine for a beer and pretzels midweek quick evening game.
After checking out interest at my local club, we have 1 person for FSA, 2 for US and at least 5 for DW. So that definitely swings it in DW favour for me- reasonable chance of getting game in at my local club.
Only 1 person has DW land force, but all 5 have DW Naval force. Fleets include Brits, Prussians, EotBS, and CoA. I was liking the Brit Land force but for Navy I was torn between FSA and French. So the good news is whichever I choose it would be a Fleet not currently played at club, thus giving me good variety of games. I will check out Naval Starter packs for those two and decide which one I prefer the most.
