Pretty interesting first episode. However, I kept wondering about one very important aspect of this setup: how were the player's bodies being maintained for the month they spent in the game?
There was no indication that game time runs any faster than real world time (unlike AccelWorld), which would mean a month spent in the game is a month in real time.
Did the surviving players all get feeding tubes, catheters and nursing care in the real world?
I imagine they will have to explain it next episode.
Seeing more female characters in the ED was something else to look forward to.
