I have played plenty of SBH over the last year-and-a-half and recommend them thoroughly, but with a few caveats. Firstly I completely ignore ALL the stats for Personalities and Warriors given in the various books and a good number of the Special Abilities/Rules as well (some of which are frankly not very useful/awkward to use
et cetera. Simply put there are far too many and they detract from the very simplicity of the rules mechanics which is the selling point of this system. For instance the only Special Ability from the
Song of Wind and Water supplement I permit is Sharpshooter!).
I create army lists for each 'race' using the
Warband Builder tailored towards both the setting I have chosen (in my instance, somewhat unimaginatively, the Warhammer Old World) and what miniatures I have available. This avoids some of the unfairness that Phreedh mentioned earlier (for instance my Zombies are Q5 C2 Short Move, Undead. Crap, but not totally hopeless. Actually my Imperial Militia have a Q6, but we only use them for comedy value) and also allows you to create some really hard-as-nails Personalities which I feel the rulebooks lack (this is fantasy after all, right?). I have also written my own scenarios (four finished and one nearing completion) which I and my minions feel are much better than anything given in the rulebook. With these considerable modifications, then, I feel that SBH is a very elegant and fun system that I'll continue to play into the foreseeable future. I do hope to get Havoc at some point (I see it's now available as a download) as I've heard some very encouraging things about this set, but until that time SBH it'll be!
Hope this helps a bit! By the way, I am tarting-up and putting my SBH scenarios (not setting-specific) onto PDF format so if anybody would like to check them out let me know.
