Hello! I'm your local adorable rodent, I've played on City of Heroes on and off since City of Villains was released. Likewise, I've played on Champions Online for some amount of time prior to its evisceration acquisition by Perfect World Entertainment. I can't speak to what the high point of City of Heroes was for me, but the high point of Champions was Vibora Bay in my book.
I've loved both superhero MMOs that I've put time into, City of Heroes for its entire run and Champions while it was in its prime. I'd love to see this game thrive as well. Altogether, I'm looking forward to see where this goes!
