One of my favorite features of MMO creation is the fact that there are no real rules regarding gameplay style. Granted, in the early days of MMO design, a creator had to consider the heavy latency of dial-up connections, so most games were designed to be turn-based. However, now there really is no limit to gameplay style, so there are no rules regarding what makes a game an MMO besides its having a persistent online world. There are no rules that say a game must have similar gameplay to other games that came before, even a prequel. Guild Wars 2 is a great example of this, yet people, inevitably, are going to attempt to compare Guild Wars and its sequel -- sometimes to the point of being unfair about it.
Current Star Wars fans cannot help but compare SWTOR to Star Wars Galaxies. Follow me after the break as I make an attempt to debunk this stigma.
