A lot of things that felt like plot threads never got resolved, although I’m not sure if all of them were actually full-blown plots to begin with. The thing I was most upset about was the thing Checkers told me I should look for, and Freefall’s involvement in that–that definitely seemed like the beginning of some larger plot, and then it just…ended.
Also, I felt like the ending point was kind of arbitrary–I stuck around, and it didn’t feel like there was any particular reason I couldn’t keep looking.
