Despite graphical handicap, this is probably one of the best mofo games ever! 100% fun, thinking what I would change left me with nothing. Well balanced, interesting, huge variety of weapons spells and enemies will keep you on your toes, and making you pray to survive. Even on easy survival is not guaranteed, a game from back when games really were games, and not money milking programs.... And, you can use it with Reshade, to enhance graphics even a bit, but it's a bit tricky, you need to use a program called DGVoodoo so it connects to modern directX, but I made it, and it looks sweet:

Sadly couldn't make it work in widescreen.
PS. I don't consider it a horror game, sure there is gore and dismemberment, but same goes for Skyrim ;)
