I've played AWI games during lockdown over Table Top Simulator and prior to that used on the real table top for AWI and SYW in the Caribbean and for other periods including 1848 and 1860 Italy, Crimean War, 2nd Schleswig Holstein War and Franco-Prussian War.
I really like the rules and the games have always been enjoyable with them. The officers characteristics and background usually make for an interesting extra dimension and the double 1/double 6 events often throw something unusual into the mix.
Best of all, no chits, counters or other bits on the table. Flexible set of rules, well worth a look.
