Thanks for that information, Northpin and Rat Catcher. I didn't know anything about how the consoles work with regards to this game and now I have a better understanding. It sounds weird to hear that some people have to pay to play this game while PC users don't. Is there some kind of overhead that is covered by Sony and Microsoft to justify this fee?
Technically you pay for a controlled environment with close to absolutely no cheating and centralized blocking.
Their policy on cheating can go as far as bricking consoles.
Also there is the advantage of playing in a more level field since you are limited to whatever controllers are supported on the platform and no 3rd party stuff, no macros, no scripting.
There is also an advantage, one can create multiple XB/PS accounts and play the game on many alts (on PC you have to buy another account) on the same console - but that does not compensates for the monthly subscription required to pay for playing in PG or Open.
