Voices

A solo developer with 14 years of Unity experience decided to exhibit for the first time, drawn by the festival atmosphere and the closeness to creators after attending as a visitor (from Shunsuke Ohba's report, in Japanese)
A TGD6 exhibitor reported roughly 2,000 visitors and constant crowds, praising the shared space that helped hand out 600 flyers and valuing the event for developer exchange and deadline-setting (from an exhibitor's report, in Japanese)
