There’s a part in Lord of the Rings Online that sticks with me. When I finally got out of Moria and went to Lothlorien, Frodo is there. The game has a mechanic where when you’re in the presence of particularly strong evil you get a debuff called dread that lowers your morale (essentially your HP). When I approached him I noticed I had a dread debuff and was confused as to what was causing it until I remembered - of course, he has the ring! The game doesn’t make any mention of it, it’s just left for you to notice. It was a great way to subtly depict the burden he would have to carry for a long time.
