I read an article in another website about what video game questions could be answered by 2040. I thought of compiling my own collection of predictions, so here goes.
By the year 2040...
Advances in technology made it possible for gamers to have total immersion in a virtual simulation in which games can be played.
Annual gaming tournaments will be as televised as the Olympic Games, and will have a worldwide audience.
Game developers will double as movie producers and directors
The conventional means of social interactions will go the way of the newspaper, and the majority of people will prefer spending "quality" time with their peers pwning others in their game of choice. Face to face interactions will be viewed as a fancy alternative to the norm (similar to how most of us view the people who still read print newspapers every morning).
Game achievements will be considered by potential employers in your CV.
A new form of social segregation will be seen emerging in some circles, built around the pro/noob and/ or hardcore/casual gamers.
Game consoles will continue evolving, with each new generation providing more features until the inevitable cross-compatibility consoles can play each other's games, forced on the gaming industry by increasingly empowered studios to maximize their profits.
A massive gaming world will be built, almost to the scale of 1:1 of Earth, which has geographic locations for different game types, with gamers able to travel (although with some difficulty and item monitoring to ensure the balance issues of different locations are kept,a-la airports) through different genres and settings. Although, you will find some people trying to smuggle healing potions into the futuristic militarized dystopia area, or smuggle firearms into the fantasy realm to try taking over Hyrule. Read the little-known novel Epic by Conor Kostick for a little preview of a world run by a glorified MMO.
Future conflicts will be resolved through FPS or RTS battles.
As games become more mainstream, you can expect more games to have heavy-handed religious and political messages.
Reality TV shows will make place to Reality Gaming Show, where contestants are sent to an unfriendly virtual environment under varying degrees of disadvantage to compete for a prize.
In-game currencies will have an exchange rate with one another, as well as real currencies. Fifty Wasteland Bottlecap equal one Hylian Rupee, which equals 1.8 American Dollars.
That's all I have for now. If you have other ideas, please post them in the comments.
