So i used to dabble in doing jobs for Amazon’s Mturk work system to try and make some extra money. I’m not gonna go into the details of what that is or how it works here, but we would get a lot of little jobs that could be “write out closed captions for these short videos”, OR “select any squares of this image that meet the request”, like on this post. We’d be allowed to not select any squares if that was the case. They always looked like screen shots from google earth or something. A lot of times, like here, the solution was not in the provided image. I always felt like us Mturk human workers were providing the solutions to these “anti bot” measures.
I played through all 3 games again back-to-back a few years ago (having previously only played separately as they released), lots of stuff tie them all together and loop back to familiar scenes and incidents from different angles and times, even a 2 part DLC for Infinite. Basically looping back to where the first game starts that kinda makes it an Infinite story loop…very well done.
Also, there’s a book that prequels the first game- tells the story of Ryan building Rapture and how it all got started. Lots of back-story and lore on quite a few characters…especially “Fontaine” and how he ended up as the fish merchant…
