Other Final Fantasy Hair Style & Gear/weapon.

They should add all the final fantasy dissidia outfits in game. More i prefer to use is the one tidus wears.
Shirtless

and non shirtless one.

His arm guards and weapon are pretty awesome and would be glad if its added into game.

Since Cloud's Armor is now a part of the veteren rewards . . how about:

Indeed.

I don't think I'd mind seeing some of the glamors and character creation things mentioned in this thread added to the cash shop as long as it doesn't start to go overboard, because obviously they aren't gonna make crossover events for all these games and the ones they do make probably won't be any more extensive than the lightning event/rewards. Personally I'd rather see them keep putting most of their effort and resources into updating the game with lots of original xiv content with the occasional fan service GS or veteran reward or advertisement event on the side, with about as much focus on the cash shop as we currently have.

Would be nice to have some of the hair styles from past ff's though, but we've been getting new hairs regularly so it wouldn't be much for them to slip in a bit of fan service at some point.

I'm all for adding new hairstyles but personally I would prefer them to be more in the direction of quest/event rewards.
