Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Projects In Progress [GM Map](WiP) Tristram (Diablo)

Hehe judging by picture 4 and 5 it looks like the Cyseal cathedral from the first game, so a D:OS 1 remake.
But then again the first picture look eerily like a little town called Tristram, plus the grey atmosphere and the sinister cathedral all point to a Diablo remake.
