I was interested to see that 'Shugyosha' of the 'Wargaming Everything' blog has embarked on an ambitious endeavour: 'The Ultimate Napoleonic Wargame Rules Review and Comparison'. Especially happy to see that he (I assume 'he', but forgive me if I'm wrong) had some very nice things to say about BBB:
"When thinking of the biggest battles of the era, [...] BBB makes it actually possible in a manageable time frame. [...] Among all true army level systems it is probably the best middle ground between playability and period flavor. This might sound like a compromise, but it is not. BBB stands on its own, and for me among the very top.".
Ultimately it's a matter of taste, of course - but I'm glad BBB is to Shugyosha's, and I very much appreciate him taking the trouble to share his reviews of BBB and many other rulesets in this way.
Oh, and I had to look up 'Shugyosha'. Now I know it means a samurai warrior pilgrim. Thanks, pilgrim!
