From what I've heard of the game, it's likely it will be based more on City of Heroes than HERO System.
* Your powers, on your terms: There are a multitude of astonishing powers to choose from in Champions Online, and its flexible character creation system gives you total control over your hero's abilities. - The real problem - what is the range of 'total control' we have? Do we have a point-based system or is it yet another level-grinder? We just don't know.
* You can even pick the appearance of your powers. Do you want purple force fields? Green fire blasts? Jet black claws? In Champions Online, you decide! - You mean we can pick the color of our powers? Wow.
* Vanquish evil, and your successes will be rewarded with costume pieces to enhance your powers and abilities. Then customize the appearance of those rewards to your vision of your hero's look and abilities! - GRIND GRIND GRIND GRIND THAT PERFECT OUTFIT
* The story of Champions Online is constantly changing, continually evolving. Villains are defeated. Heroes rise and fall. Cities transform. Your actions may decide the future! - There will be 'story missions' every two months, then every six-to-eight months, then they'll say ' fuck it' and fire their story department.
