Some years ago, I picked this book up in a $1 bin a used book store
https://www.amazon.com/Kitcheners-Sword-arm-Archie-Hunter/dp/1873376545/Not only are the battles rather well-described, but also well-diagrammed.
However, I'd read it at a time when I was more focused on RPGs than wargaming, and never went looking for any games on the battles. There's plenty of stuff out there on the Boer War, but not so much on Hunter's campaign in Sudan, and not a lot about the battles in India (though those would be tougher to game at a lower level).
Any idea what games might be out there for a good look into Hunter's Sudan campaign?
Any good Boer War games that specifically focus on his actions in South Africa?
