… play as online game?

My personal would be:

1. Final Fantasy X-2 (at least you can ride CHOCOBOS here AND play Blitzball AND play Sphere-Break :D)

2. Final Fantasy VIII ('cause of Triple Triad Cardgame and awesome world, may be now in HD :D)

3. Final Fantasy XI (Tetra Master is really nice)

Tell me your best choice too, please :D!

Well lets see…

1. FF VII, VIII, IX - The minigames. I've read this from various forums, and I would agree that I would like to see something like the Golden Saucer from VII as a central arcade hub for various mini-games, whether it is card games, a snow boarding simulation, etc.
2. FF IX - Combo skills, such as the ones between Vivi and Steiner.
3. FF X, X-2 - Agree that I would like a sport like Blitzball. Probably would choose something closer to X if possible for more direct control of the character.
4. FF III, (as well as others) - A wider selection of jobs. Granted, I haven't exactly hit the max on any jobs/classes on XIV right now, but I would like to see a bit of diversity, maybe with their own stories, AF gear, and such.
5. FF various - Summons! Whether you call them Summons, Avatars, Espers, Eidolons, Guardian Forces, Aeons, or whatever else, I would love to see some sort of summable force (such as Ifrit, Shiva, etc.) to use. And no offense to XI SMNs, but I do hope they will be more powerful than their previous online incarnations. If they get creative and allow them to be used in multiple facets, such as like vehicle types in XIII (but actually be able to use them as vehicles) then all the better.
6. FF VIII - I would enjoy some sort of organized military missions (or assault type missions from XI). The example I am thinking of is the assault on the president's train. In the context of XIV, maybe have one part of the party delay the train through some actions that would allow the other part of the party to board it. After a little fighting, activate a crystal to allow the others to teleport in, and then fight your way through the cars to the boss. I can think of two tracks for this train to take (pardon the pun); they could either keep the military theme and have the Garleans control the train, or maybe bring back Ghost Train from VI, and give it something of a horror theme with Ghouls, Bogys, and the like.
7. FF VI - Thought I was done, but just remembered one more, and this is one they teased at before XIV even hit Beta. But I would like them to fit in something like Magitech armor. Granted, there may not be any immediate need with it as we can teleport to so many places at will, and there doesn't seem to be any big boss fights just yet, at least from what I can tell from the forum chatter on other sites (can't speak from experience as my highest job is currently a rank 27 PUG), but as the game grows, I do hope they follow through and add it in a fun and effective manner.

And I guess that is it for now.
