If you enjoy materialistic capitalism, you will enjoy the World of Warcraft. Underneath the dragons and magic spells, WoW is a microcosm of America. If you want to fully enjoy the pursuit of happiness, you must fully engage in masochism. If you did institute differing economic systems, moralism aside, we could learn each system's tactical differences. People often argue for communism as a system of virtue. It is ironic, because communists are typically more atheistic. Moralism is a philosophical religious notion utterly destroyed by evolution (appropriately enough, as evolution functions specifically to destroy what is rubbish, clearing space for what isn't).

World of Warcraft isn't all bad. The people are assholes, without exception (other than myself). The game world is moderately fascinating. It is a working ecosystem, of sorts. It is like a primitive civilization and a base animal world. I despise the fact it is entirely American. The word bland comes to mind. Is it ethnocentric or unimaginative? It is definitely narrow and rigid. The differences between factions are practically superficial.

In summation, I would say the system has potential. In its current state, it is little more than a shiny toy, useless to anyone who values their time.
