Restating the Obvious

I stumbled upon The Tulse Luper Journey tonight, but I'm still not completely sure what it is. My knowledge of it boils down to the following:

• It's an online game.
• It's entirely free.
  
• It follows the journey of Tulse Luper.

That's about all I've got. This site explains the concept a little better than I have feebly attempted to do.

Hell, the game kept me awake an hour or so past my bedtime, so it can't be half bad.
