The Incident and the promise

Just noticed a game pretty much close to the novel I intended to replicate later but the game was much simpler than I intended to make, only a few people knew about its existence a few years back, and since my pc doesn't support the game so I kinda forgot it. the name of the game is Panzer Knight where you play the role of the Geman Panzer's crew during its early Poland war to the Late-ending war of the second world war.
