Full disclosure: I am in the core organising team for Wikimania.
For one evening only at Wikimania 2014, there will be a huge gaming event known as the Wikimania Games Corner. For one night, there will be a dedicated space to play a variety of games.
As far as electronic games go, you will expect to find Mario Kart Wii(Nintendo Wii), OpenArena(PC/Linux/Mac) and Streets of Rage(Sega Mega Drive) to name but a few of the games that you can play.
If you’re really lucky, you might be able to get your hands on the Elite: Dangerous beta and get a taste of the game before anyone else.
There are also going to be tabletop games including Chess, Imperialism in Space and Once Upon a Time.
Of all the various sessions and talks etc. going on at Wikimania, you should be really excited about the Wikimania Games corner. This is because you will be able to enjoy a wide variety of games and play some that you’ve never played before. Alongside that, there will be a retro gaming arcade section where you will be able to play retro arcade games such as Donkey Kong, Space Invaders and Pac-Man! I think, that of all the entertainment on offer, this is probably going to be the most popular event in the Wikimania programme.
Wikimania 2014 is a 2000 + person conference, unconference, festival, meetup, workshop, hackathon, and party, spread over five days from 6 to 10 August 2014, preceded and followed by fringe events. There shall be a full programme of talks, workshops and discussions where you can learn about what people are doing and how you can take part.
You can buy standard registration tickets for £50.00 which includes the three day conference and opening ceremony. Single day tickets to the conference are £30.00 and include lunch. Early-bird tickets and hackathon tickets have sold out.
