Game localization is a vital function of the ever-expanding global game industry as it's responsible for half of the industry's total revenue stream. Successful game publishers and developers realize that localized versions of their games can drive revenues and increase international appeal. Beyond existing gaming markets, the demand is quickly increasing from a growing number of countries and emerging markets around the world, which is prompting publishers to localize and even culturalize more titles into more languages to maximize their ROI. The game Localization Summit at GDC is supported and organized by the IGDA Game Localization SIG, and it is aimed at helping localization professionals as well as the entire community of game developers and publishers understand how to plan and execute game localization and culturalization as a part of the development cycle. Professionals from all departments and all areas of expertise are welcome to attend this full day of lectures, panels and game postmortems.
