Don't even get me started about that little trope! I hate it when there is a lack of handrails over a chasm where they have no right not to be there! I absolutely loathed it when I encountered areas while playing Star Wars Jedi Knight and Jedi Academy that lacked any hand rails, and as fun as it was push baddies down to their deaths, I was always afraid of accidentally overstepping and having my character fall to his death, and I couldn't help but think how terrifying it would be to walk through those areas in real life, unless I had wings or could otherwise defy gravity.
