While on my way to purchase the new FoG II DLC, two games from Yobowargames are in the front page of Slitherine. There was very little talk about these games.
Korsun

Interestingly, Slitherine/Matrix are barely mentioning the game themselves. There was no announcement for it, they added some forums and the only topic is someone asking if it supports Windows 10.
In any case, this looks to me like an iOS port. ???

Yobowargames is basically a one-man band who's been making hex-and-counter style wargames for a couple of years now. Mainly for iOS but he's ported them to PC too. I think his current claim to fame is that he's working on a port of Valor & Victory for PC and potentially mobile.
We've been keeping an eye on him so coverage is around if you want to go looking for it. Nice to see he's getting some support.
