Nathan Grayson, for Kotaku:

The fantasy RPG plops specially selected players onto a single server and divides them into two teams of four. This means only eight players will ever be playing Upsilon Circuit at any given moment, and their adventures will likely come to swift, brutal ends. Sounds terrifying, right? Every move you make can literally be your last.

On top of that, the game will have a participatory audience watching live, something nearly as cool as the “one death ever” conceit.

Spectating (possibly from beyond the grave) is just as much a part of the game as playing. It’s a fascinating social experiment, and it sounds like the developers are just as interested to see what happens as the mortals who jump into the ring.
