The GX3: Everyone Games convention will take place on December 11-13, 2015 in the San Jose Marriott in San Jose, California, GaymerX’s has announced.

Those who backed the event on Kickstrarter should get a ticket code in their emails by the end of the day, but you can also buy tickets from the GX3 Eventbrite page at a special pre-sale price. Starting on December 17, GaymerX will also put up a booking page where you’ll be able to get discounted rooms at the San Jose Marriott.

“Not only will GX3 have incredible guests, including one of this year’s Bosses of Honor, the voice of Commander Shepard from the Mass Effect series, Jennifer Hale, but we’ll also have a grand host of gaming festivities for everyone, from panels, tournaments of the gaming and tabletop variety, live music, and cosplay,” GaymerX said. “You’ll also have a chance to play games from some of our sponsored attendees, too, and hopefully some really cool games made at GXdev!”

Other “Bosses of Honor” announced so far include Zach Weiner, creator of webcomic Saturday Morning Breakfast Cereal, Ellen McLain and John Patrick Lowrie, voices of GLaDOS and Team Fortress 2’s Sniper, and Rob Jagnow, co-creator of the hit games Cogs and Extrasolar.

The organizers’ official name is still GaymerX, but this year’s convention is nicknamed GX3: Everyone Games to make clear that everyone who’s 18 or older is invited.

This year’s convention was successfully funded on Kickstarter in September with just a day to go. It eventually raised $97,917 from 999 backers.
