Fair enough, I'm done.
I really do think an enhanced social presence would do a lot. The Producer's Letters and community reps are nice, but the free advertising stuff like Twitter and Facebook can offer is pretty hard to argue with.
I wonder how important it might be to go after the fanbase who left? I mean, what about some sweet extras for those who get the PS3 version, or an FFXI event with a FFXIV re-release theme? Maybe like some tie-in what-if storyline? I'm not entirely sure it'd be worth SE's effort to market to XI players, as I imagine there's probably a lot of overlap already, but maybe enough have gone back this would entice them to give it another go?
Maybe throws in free trials with other Square Enix releases? In this day and age, it wouldn't be hard to have the PS3 version downloadable as well, maybe throw a free month trial (assuming they're charging by then) with releases like XIII Versus or -2?
I also liked Rift's comic book prequel tie-in, and their "We're not in Azeroth!" anymore tagline, but I don't know if that's a direction SE would like to go.
