We already have many games (The Forest, Slender: The Arrival, [Minecraft and others) that are revisited becuase of a new version or personal reasons, the videos are numbered in a single order of release for the games, and a note can be added explaining the difference from the previous video in the list.

More technically, it's not "one solo and one co-op", it's one 2016 playthrough, Mark restarted and decided to invite Bob next episode, and a new playthrough that just started.
