“I, Julius Caesar declare this game to be rather fun. This game itself has a wonderful sense of atmosphere, creating a dark and dreary setting. However, it often succumbs to the ill fate of the dreaded Memory Access Violation.”

“It's a fun novelty with friends for a bit but I wouldn't recommend it for experiencing the main game proper. Way too many weird glitches that weren't in the original.”
