Typically, such games allow users to create characters (avatars) using character attributes (hair color, eye color, skin color, attire, weapons, etc.) The game operator keeps track of the popularity of each attribute by tallying how many times it is selected. The same such systems and methods may also apply to games that permit users to create custom sceneries.
This seems to be the section of the patent that would include Aces High.
Overall to me it seems that they are trying to scare up some income, however since their patent appears to have been issued on May 15, 2012 I don't think they will gain much traction. The only real question seems to be (and perhaps Brooke can help here) whether the Priority Date being Jul 12, 2000 would be an issue.
