Alright we all know the deadly addiction to the crack game known as World of Warcraft. Then you have games like DC Universe, City of heroes, Everquest and much more. and the past 5 years theres been all kinds of underground projects coming out of the wood work all over the place even on smart devices.
What one are you playing?
I found one on steam that is pretty cool and free (for now atleast).
APB Reloaded. Best way to describe it is Grand Theft Auto in the form of a MMO with all the violence and vulgar language and rough cut attitude.
the games world is split between 2 factions developing a kinda Cops and Robbers appeal to it.
