Hopefully you’ll be able to input things like newspaper articles; Current Events, Job Listings, Personals (to find people to kill as no one would miss them), and maybe if any of your killings are on the headlines.
Conversations with co-workers, neighbors, etc. would maybe give insight on what they like to do, work, etc. like in the video where the guy killed the guy who was watching TV (Civilian A may like watching a comedy show every night at 10:00pm thus, they’ll always be watching, it which may play to your advantage).
This game, when it gets released by OP, will be GLORIOUS.
