Okay, okay, just the Congo I'm afraid. No Um Bongo.
I've seen that Studio Tomahawk are working on a colonial/Darkest Africa set of rules called Congo. you can read more about it here. If it's even half as good as Saga and Muskets & Tomahawks I'll be a very happy bunny and a regular player - I'm looking forward to it already!
Hopefully, with both The Men Who Would Be Kings and Congo publishing in 2016, it will be a good year for colonial gaming next year!
