A custom pack replaces the game's built-in content with the team's own — in-jokes, company trivia, a theme for the week. Only these three games take custom packs; for any other game, say so rather than calling this. Send the content in the one list that matches pack_type, and write it to play well (see each list's description). The host picks the pack in the lobby before pressing Start. Custom packs need a Pro or Business plan, which caps how many a team can keep — call funfriday_get_team first if unsure.",
