To complement what Sub was saying, the overall design of the game seems to center around group play, much more so than any other game I've ever seen. And they got it right. There are very few things that can't be done better in a group.
You CAN play solo, and do quite well, but just understand that the game is not centered around, nor really catering to, the solo player.
