why would you mod it out? its the perfect opportunity to correct your fear!!
It cannot hurt you from a video game, just keep that in mind lol
it doesn't work that way for everyone though, i know ill mod spiders out day one for a friend of mine. She saw a some bugs crawling on the ground in a movie we were watching, thought one of them was a spider, and passed out.
Arachnophobia is pretty common, and its a bigger deal to than a lot of phobias i think because spiders are already creepy to a lot of people, and people experience height and strong winds and water and a lot of other things they have phobias of every day,
but how many people have frostbite spiders drop down on them from the ceiling of a cave all the time?
