There really is no sane reason to spend hundreds of US$ or Euros in this game at all. It is 7 years old which means it is woefully obsolete compared to its competing games. The novelty of the new races wore off very quickly when it was seen how poorly it was integrated into this game.

There really is only one reason to spend so much of your hard earned money here: It is a total unreasoning obsession. It really has nothing left to redeem it.
