I have been giving considerable thought to this topic, and have bounced some ideas off other former players as far as the return goes.
These ideas are acting under the assumption that character/account data will not be available, and our new Freedom Phalanx secure a launchable version of i24, with all the trimming leading up to it (The Paragon Market and all related systems).
Bear in mind that no matter how noble it may seem, bargaining for customer's account and character data is essentially one company SELLING PERSONAL INFORMATION to a third party. I would be flabbergasted if it all goes through that way.
NONETHELESS! When (if) the game is revived from these efforts, whether or not they are to continue development on the current incarnation, or begin development on a "CoH II" a hybrid Free-to-Play/subscription model should be kept in place. This will become clear as I detail the rest.
Upon launch, MUCH FANFARE! EVENTS! FUN! CITY OF HEROES IS BACK WOOOOOOO!!
Free to play will remain as is, as will the perks associated with Premium Accounts of yore. Subscription model will follow 14.99/month with discounts for bulk purchasing (buy more time and SAVE!) but instead of the 400 Paragon Points (hereafter known as PP), supply 800PP with each recurring month subscription. This will encourage people to subscribe, while also allowing people to pick up on the backlog of shinies or gather other perks.
Now I hear you say: "But Ouul? What about all my STUFF!?!"
Now, again acting under the assumption that it is gone, poof, out to pasture, it would be of great disservice to our long term veterans to have them start again from ABSOLUTE scratch, so I propose bundles and packs at a reasonable price to assist! These packs should encourage early adoption, and be available for only a short time after the re-launch (60-90 days) and then again during event weekends and as special promotions.
VETERANS PACK: $49.99 - Return to Paragon City and the Rogue Isles in style! This pack will bestow upon you enough Veteran Rewards Tokens to pin your way to the top! This will allow you to unlock all veterans rewards, plus the limited time costumes at the top tier!
BOOSTER PACK BUNDLE!: 49.99 - INCREDIBLE VALUE! This pack includes all the booster packs released, from the 5 origin packs through Valentine's, Pocket D VIP, Wedding, Mac Edition, Going Rogue Bonus Items, Origins, Steampunk, Party, and Animal Pack!
DELUXE EDITION BUNDLE: 9.99 - This pack includes the items from the CoH AND CoV deluxe collector's editions
And to help with levelling one's characters back to their prime:
CHARACTER BOOST BUNDLE: 4.99 each - This will come with XP Boosters, Team/Dual inspirations, and a 30 day temporary JetPack
Once again, this is just speculation and brainspewing to provide some ideas to go off. What do people think?
