Lets talk about Pathologic PC

Pathologic is a unique example of a dramatic game, which directly affects the player’s state of mind.
…In the depths of the Ancient Steppe appeared a weird town. Once a small drover settlement scattered around the monstrous Abattoir, it unexpectedly developed into a mysterious, isolated establishment with an odd social structure. This odd society has managed to survive for several generations. It could have continued to aspire, were it not for a sudden outbreak of some enigmatic, lethal and inescapable disease, which begins to mercilessly slaughter the denizens inhabiting the area. Even science has proven helpless in finding a cure, or at least providing some explanation.
