Some game has the blurb in the game. You can read the blurb without leaving the game. I should give it a score of 10/10.
Some games make the blurb available via an optional link. Amusingly, for one such game, I played the whole game through before I tried the link with the blurb.
Other games print the blurb at the start (if you use an interpreter like glulxe which displays metadata). I prefer that the blurb is made visible immediately because it puts the game in context and in case the blurb contains content warnings.
