Description:Soon after Princess Luna tried her first-ever video game out of boredom, playing them became her #1 favorite hobby by far. She especially loved playing them with other ponies. It was just too bad that her competitiveness and hot-bloodedness made ponies start "conveniently" claiming they felt ill when it was their turn to play with her.
However, Princess Celestia could tell the real reason, but couldn't bear telling her little sister out of fear of giving her Nightmare Moon flashbacks. Near her wits' end, Celestia asked Princess Twilight if she knew any ponies with both a fondness for video games and a personality capable of handling "Gamer Luna."
At Spike and Starlight Glimmer's suggestion, Twilight decided to ask Eric Reed, a human but also an experienced gamer, to be Luna's new gaming buddy. Unfortunately, Twilight forgot to warn Eric that Luna could become intense when she played games, which accidentally left him blind to what he was in for.
Things (probably) went as well as you might expect.
