I like games for three players. It's an often-awkward player count for other games, thanks to the inherent instability of games falling into a 2vs1 situation, so those purpose-built for it tend to feel special. The King is Dead, Trieste, Maria, Three Kingdoms Redux, and so on. This one came to my notice as a result.

Brotherhood & Unity is a 2-3 player card driven wargame which depicts the war in Bosnia and Herzegovina from 1992-1995 ("Bosnian War"). The game shows all of the major events: from the siege of Sarajevo (shown in separate, detailed map), to the ferocious battles for the Posavina corridor, and desperate defence of the Bosniak enclaves. Main features are: Point-To-Point movement system, play driven by Strategy Cards, quick combat resolution (no CRT), streamlined rules and fast gameplay. Interaction between warring sides (Bosniaks, Serbs and Croats) creates an intensive and exciting gameplay experience.
I love CDGs anyway, so I was sold fairly immediately. While it has many shades of Paths of Glory in its systems, it also has three different sides, Serb, Croat, and Bosniak, and if any one of them is too successful they get malleted by NATO airstrikes. There are UN safe zones, refugees, foreign fighters, and supply lines to take into account.
The designer posted a helpful guide to the place names, which can be challenging for English speakers.
It shouldn't take too long to play by the looks of it, and it's a challenging subject to cover.
