The world's top gaming promotion event, Tokyo Game Show 2009, kicked off Thursday in Chiba as key developers unveiled new titles to hold on to consumers reluctant to spend in a recession.

The four-day expo at Makuhari Messe convention center will see 180 companies and groups worldwide showcase more than 750 game titles, said the expo's organizer, the Computer Entertainment Suppliers' Association.

This year's show was expected to have 1,367 booths and attract about 180,000 game fans who will be given hands-on experience with the latest titles, such as the Square Enix Co.'s latest edition of the "Final Fantasy" series for the Sony PlayStation 3.
