Too many adds.
This game used to actually be fun to play, because you could play a full game without an add. There were still adds after a game was over, but that was tolerable. Now they have changed it so there is an add EVERY TIME you reach a higher number achievement. It is so infuriating. I used to play this game all the time and it was a lot of fun, but now it is just god awful because of the inability to play a full game through without an add. Disappointing.
