It was dark. All of a sudden I heard a growl that sounded like it was in the room with me. I knew it was the game, but still had to look over my shoulder (just to make sure).
Some of the sound effects were very realistic.
This wasn't scary, but startling. Recently, in Lotro:
An RK and her (non)protector, near the end of Storm on Methedras, the hut falls apart and out jumps
. How am I gonna kill that!?!
Lightning is good.
