It is not necessary! General admission tickets grant access to talks on the Journey stages, the main stage of the event.
However, only B2B and Start Pro credentials provide access to talks on the Insight and Connect stages, which are for game professionals and are more technical and in-depth.
Additionally, only participants with a B2B ticket can book and secure seats for talks of interest through the official platform.
