All I have read is that sales exceeded SE's expectations.
Also, I wouldnt listen too much to all of the negative commentary on Zam. For each negative poster there are lots loving it in game. I reckon I must have grouped with in excess of 100 different people, and been in my LS with in excess of 50 people and whilst most say the game has issues that need fixing, all intend to resub.
Internet forums by their nature are populated with those with strong opinions - most people that like the game are too busy playing the game. I only access Zam these days when Im not home to play (sadly my laptop cant handle the gamee and lags too much).
