Silverlined Productions has released the trailer for Revenge (Act 2). This is the follow up to the first piece of roleplay inspired work, called Revenge. In Act 2, Nixxiom is finally getting his chance to show down against the Lich King. That's pretty appropriate, when you consider the likely proximity of patch 3.3.
Interestingly, in the Myndflame post about the video, the author is pre-emptively defending his work against accusations of "god mode." That's a roleplay term in which the player considers their character so awesome, they win every encounter, and possess every virtue. Generally, in machinima and fan fiction, that dynamic is called "Mary Sue."
I'm not sure the trailer itself provides any defense against accusations of Nixxiom being a Mary Sue. You can't really make that call until you see the final movie. However, since it is a roleplay thing, and roleplay tends to be an escapist art, I think it's fair game to do a little idealization of the character. In the end, it really all comes down to how well the author can tell a story. Here's hoping the final film does the confrontation justice.
