there is a free trial, I don't see a need for a money back guarantee.. I tried the trial bought the game and played it. If I like it in the first hour and buy it then decide i don't like it later thats my own fault.

As far as negative responses from customer service goes they are generally recriprocal. If you treat others respectfully you will usually be treated respectfully back. If you are rude condescending abusive or demaning their talent at creating such an enormous project like this game is then you probably deserved whatever response you were given.

never really paid attention to the differences between the other games, took this one at face value and went with it. It is a different game with different tasks, goals, and ways to achieve success. there are things i don't like about t but its all part of the game. Play it, don't play it, but when you buy something if its used you own it IMHO
