Celebrated game designer Ron Gilbert will be opening Australia’s Penny Arcade Expo with a keynote address, the company has announced.

The Monkey Island creator and current Double Fine designer will be providing the opening 'storytime' keynote on the expo’s Friday morning.

Outside of Monkey Island, Gilbert is probably best known for his work on a number of beloved LucasArts games including Maniac Mansion, Day of the Tentacle, Zak McKracken and the Alien Mindbenders, and more recently DeathSpank, and The Cave.

Ron joins other international guests confirmed for PAX Australia including musical acts The Protomen and MC Frontalot, the RoosterTeeth crew, and of course everyone from Penny Arcade.

PAX Australia will be the largest gaming festival to be held in Australia, and has already sold out of three day and Saturday passes.

It will be held at the Melbourne Showgrounds from 19-21 July, 2013.
