I personally enjoy Final Fantasy games, and I REALLY enjoy MMO games, so I really don't want to see this one die!
So here is my opinion on what SE probably should do to save this game, and potentially their Final Fantasy brand.
They need to recall all the unsold copies of this game. Put this game back into BETA stage, give everyone who already bought the game access to the beta (and not charge them again for the game when they RE-RELEASE IT). Take feedback from the community (I know this is hard for you SE). Then set the release date for the PC version the same day as the PS3 version. Also, I think they should openly apologize to people who did buy this game expecting a whole lot more than given. What they are doing now (not saying anything to anybody) is making things worse for them. They should have realized that MMO's are 100% community based. If the community doesn't like it the game fails.
I honestly would gladly give SE and FFXIV another chance if they decide to TRY and make things right, if they don't well I think myself and thousands of other people will not support this game after the first free 30 days.
Please post any ideas you have for fixing this game on this thread, by some miracle maybe SE will do something. I also posted this in the feedback section. This is a long shot, but hopefully the little mans voice will finally be heard!
