I have. It did leave me with many questions, like who are the Ecumene (big E)? They are someone the Hive fought long ago, but The City card also refers to the City as ecumene (little e). Assuming we eventually get time travel abilities (like the Mysterious Exo), could we be going back in time and fighting the Hive as well (or going back in time to recolonize to avoid a future calamity, and accidentally re-encountering the Hive)?
