TBH I have jumped a lot from this game.
Falmer dropping....
seeing a dwenmer construct for the first time.
Anytime you don't see a bear, troll, or sabre before your in their "kill range" because they are up in your face before you know what to do.
Whenever I miss a draughr or anything in a dungeon and I think I'm safe.
When I find a wispmother.
When a dragon has already BOOM and landed 10 ft away from me and I'm like "WHERE THE #*&! DI YOU COME FROM?".
When all of a sudden I'm losing health because of a flying object.
Most any of the children in Skyrim are pre-psychotic and some of the advlts are freaky too but they don't really make me jump.
Yeah.... I'm a puss. I've just never played anything like this where it seems a little real and so I get geniunely startled.
