True, I had overlooked the fact that the content and progress is entirely contained online.
Must have been so engrossed I forgot where I was when I was playing.
Hypothetically speaking, being originally online doesn't preclude re-fitting a game for stand alone use. URU was originally conceived, designed and tested as online only. But that's just a musing, definitely a far fetched scenario for GumShoe. Fortunately, it doesn't have the Myst cachet pushing it in wrong directions.
I agree about the value of the game for the $5.00 - Having played through a large portion available now, I think it is a reasonable amount - assuming they fine tune the game through successive content releases.
