You know, you could start with the fact that there were no private/pirate servers. We all played the "real" game without looking for a free option.
Was thinking I'd start regaling Disney with brief stories about the parents and kids who played and more about what made CoH popular with older adults. One grandfather in one of the super groups easily spent more hours designing and costuming characters than he did in play. (Really superb outfits many of them, and it clued me into the aspect of CoH that reminded me of those into model railroads, etc.) Often late nights I'd log in to play solo and find he and his daughter chatting in Coalition. (I'd say hi, of course.) One friend came out to us one day as an Emergency Medical Technician by saying "I have to log now. Cya tomorrow. I've gotta go save people IRL." The next day she clarified that statement for us.
Since demographic data has been requested on our ages, I've wondered whether other demographic data would be useful. CoH players were diverse! I had SGmates who were truck drivers, military personnel, lots of IT pro's, students (all ages), a medical doctor (hello to Diego in Colombia), one ABD grad student (hi PW), at least one police officer, 2 EMTs, countless un- and underemployed people including those too young to work. Several of the kids grew up playing CoH; one planned to get his dormmates playing once he'd settled in at his first semester at college.
As far as I know, I am nearly the only one posting here from two very active SGs, and estimate I represent approximately 20-40 who'd resubscribe to City of Heroes, possibly more. We're all keeping in touch thus far. Even though you don't see them on Titan, many of them are mourning the loss of City of Heroes. Many of them were very active with the initial efforts to Save CoH. They all have the Disney/Team Wildcard info.
