Be generous with what you allow your players to discover information on, but don't go in depth with this information. If a character learns everything they need to know off the infosphere, they won't bother interacting with the rest of the setting! It's best to use
Access Infosphere to give general information, guidance, and clues to your players and to direct them to other
NPCs and locations relevant to the adventure—this makes Access Infosphere a useful tool for everyone.
A character can't retry a check to Access Infosphere, but they can perform a follow-up search based on newly discovered information. If a player is slowing down the game with their incessant searches, tell that player they've found all they're capable of discovering from the infosphere for now, and consider decreasing the amount of information you provide in the future.
