This weekend, City of Heroes is making things interesting, and doubling your rewards earned. Much like a credit card, this is a great promotion to bring the game into the mainstream. The current advertisements coming on for it have been terribly successful, and if nothing else, extremely funny.

"During this time players will get double rewards in the following categories:
  * Experience
  * Prestige
  * Influence
  * Infamy"

The best part is, anyone and everyone who plays can get this! There’s no special-terms of service loop like a credit card, but just a totally perfect reason to dedicate your weekend to being a hero or a villain.
