One of those games that has to appeal.
I played it for years.
There are some very clever ideas... such as mentioned in the article, you cannot buy your way to the top.
Ok.. rephrase, you cannot start a new character and buy your way to the top.
The 1st issue with the game is that it becomes very repetitive, very quickly.
The 2nd issue is that it requires the devotion of time, you cannot start a new character now and work your way to the top, simply because those who have been playing for 11 years since it started are so far advanced that you can never catch them.
Also to achieve anything significant requires a vast investment of time, the senior people in the game play for 14-18 hours a day, it's worse than a job.
