I wrote a novel about video games which I hope you'll be interested in. It's a free download for the next two weeks at Story Cartel: https://storycartel.com/books/game-trivia-catechism
Having left his quiet hometown of Arkline Falls to live it up in the big city, Al Oakenbrand unexpectedly receives a paid ticket from his cousin Sally to come home. The real purpose of his trip isn't made clear until Sally surprises him with an entry into the King of Game Trivia Tournament, a battle of knowledge for all things video-gaming. She has a plan and wants him to fulfil it: win the tournament, claim the $10,000 grand prize, and give her half the money. Al agrees for the fun of it, but, when he finds out why she needs the money, playtime is over, and things get serious. Can Al do what it takes to win while keeping sane amid Sally’s demands?
It's got a similar vibe to Ernest Cline's Ready Player One, so if you liked that then this should be up your alley.
