Voices
Attending in person adds the speakers' passion and the venue's atmosphere — an immediacy that slides alone cannot deliver.
Detailed session reports keep circulating in the community well after the event, so the learning continues.
With every game-development discipline in one place, you can touch the frontier of fields outside your own specialty.
A game programmer compared how large studios and indies approach development across sessions on generative AI and level design (from Haruneko's report, in Japanese)
An indie developer went from open call to speaking before a full house of about 150, gaining visibility and trust (from Daraneko's report, in Japanese)
