Play! was a video game symphony that brought to life the award-winning music of 20 of the biggest and best computer games around. Music from the games was performed by the Sydney Symphony Orchestra (conducted by Arnie Roth and backed by choral sensation Cantillation) while massive screens, suspended over the orchestra, captured stunning game play sequences. Play! ran  from 19-23 June and was exclusive to the Sydney Opera House. Music was performed from games including:

• Final Fantasy VI &VII
• Metal Gear Solid
• Halo
• Castlevania
• World of Warcraft
• Kingdom Hearts
• The Legend of Zelda
• Super Mario Bros
• Sonic The Hedgehog
