If you don't like this kind game of game, it'll be very short. Perhaps short enough to refund it.

If you do like this kind games, however, it'll last a good while.

As for the lack of content: things are added, just not at the pase people want it to be added. Which - reading some comments - is like: buy a game now, get new content next week, next month and the months after that.
