It's a simple game of supply and demand people. No one else is an official reseller besides the ones TX listed. They also probably have an idea that eventually a free nintendo switch CFW will come out and make TX's product obsolete. This mark up protects them from the remaining inventory once...
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
