In telltale's Game of Thrones video game, House Forrester is a family in turmoil, and it's up to you to save them. But you only get the opportunity to do so once every few months. Why? Because Game of Thrones, like the TV show and the A Song of Ice and Fire books, is an episodic adventure.
Episodic gaming has a long history, beginning in the late 70s with a game called Dunjonquest. Despite its back-story, Telltale Games really popularised episodic gaming in 2012, when it started releasing its adaptation of The Walking Dead.
Rather than make a whole game and release it all at once, Telltale released it in five episodes and called it a season. Each chapter was just a couple of hours long, but each one gave the player the opportunity to really connect with the characters and make important moral decisions. The best episodic games are like this - story-driven, single-player games that allow you to spend time getting to know the people involved.
Despite having to wait anxiously for months to continue adventuring in the Game of Thrones world, I really enjoy episodic games. The beauty of them is that in between episodes there is so much time to examine and dissect what you've done, and what other gamers have done. You can go over the best bits with your mates - or with strangers on the internet - and work out how your differing decisions changed the game.
