The same conversation Limbo started to kick off when they released that back in the day. Quite short, but when you enjoy each moment that much, how can you attempt to assign a dollar to hour value? You just can't always diminish it to something that simple.

In terms of saying whether it's "the best of all time", well, it could certainly be one of the best of all time, but you really can't put it in front of or beside games doing radically different things. Youd have to start making a few wide umbrellas of games to place together and then rank them from there. Perhaps something like Unravel would be more comparable with something like Inside or Limbo.
