Reading through the F2P restrictions, it seems like many of the things that the players of super hero games want in character customization (including choice of powers) is cut out of the F2P version. This seems more like an attempt to create an long-term free trial coupled with an effort to put more players on the field so the servers don't feel so empty.
Though after the truly awful customer service I received from Cryptic after they refused to honor the free time that came with my copy of the game, I don't think I'd trust anything they do.
I am just sad that an IP that I've played for many years, the HERO system Champions RPG game world, has been so badly bungled that Cryptic already cannot support themselves on subscriptions.
I played a little pen & paper Champions back in my youth, and was always interested in the MMO, just never heard enough genuinely good things about it to persuade me to buy. And also I somehow missed the couple of free weekends they emailed me about (always seemed to land when I was really busy and had no time to check out a new game).
Darkfall as a f2p would be absolutely entertaining. Not only for the drama it would create with the in game veterans, but the never ending blogs streaming out of certain bloggers would be better than playing the game.
Even if I wasn't paying a monthly fee I doubt that would really be enough to go back to that game. And with the slow response time to cheats and hacks that exist at times already. A f2p model would just bring a large influx of cheaters(afkers-etc) now with nothing at all to loose. AV might be slow but they're not likely to do something that unwise.
