Video games are following the easy to use, watch and forget streaming websites and embracing the digital download. Digital downloads are no longer an exception to the physical copy, they are now a primary way of obtaining new and old content.
Streaming and digital downloads are much more popular than they used to be. Following the path laid by movie and TV download websites. Its also no coincidence that video games are becoming more like movies in the way they are made.
We already see episodic games being sold as well as seasonal downloadable add-on packs. These sales tactics impact the games themselves as they are created with this sales method in mind at the start of productions. Leaving the developers to build a game around it.
Its becoming apparent that large, complete titles are fading out as the normal format for games. In favour of episodic games that have seemingly more re-sale value.
