Bloodborne. It was my first Souls game and I died at the first enemy I encountered and said "fuck it, that's ridiculous" because I did so little damage. Turned the game off, and took a year or so to bother putting the game back in. I didn't know at the time these types of games had a learning curve and thought I'd be getting your bog-standard RPG game with next to no difficulty.

Actually giving the game another shot sparked a love for Soulsborne games that I nearly missed out on.
