Is this a dream job for you? I like playing computer games (video games on the PC). I know someone is writing the characters, dialogue, plot and so on.
Writers would also be involved in promoting the game (including social media). The best people for the job would be the writers familiar with the game.
Interactive writers are the men and women who come up with the stories and write the dialog and even the text messages seen in a range of interactive media from games to apps. Often working in a team, they may find brainstorming and mind-mapping skills just as important as old-fashioned writing skills. Rather than a novel, what they produce is closer to a film or TV script.
