I've got both this game and the "hard copy" stand alone game, and prefer playing the electronic version!
For playing solo, its much quicker to set up and does a lot of the house keeping for you.
I don't really mind the limitations of only playing against a single GOO, although having more in an expansion would be great - although this would mean adding a final battle mechanic, obviously.
All in all a great product - need more like this please!
