I had a Silent Hill RP back on the old guild with a game system as well, I thought it would work much better so that characters could actually die randomly instead of having to set them up to die, which in most other Horror RPs most players will either kill characters off on purpose or make them survive everything. With a game system, that stuff is left up to fate.
Also I find that Game systems can drastically alter how a story plays out. Every character, including big baddies or epic heroes, can die and is not invincible, which adds some uniqueness to the story and allows for players to better manipulate the story with their actions (regardless of the success of said actions)
