I would pay 39.99-59.99 for this:
- Game re-balanced for 1-6 player offline/online parties, or ability to require NPC bots (make the game work similar to Final Fantasy 12)
- Leveling re-balanced and zoned for "explore as you go" style leveling
- Improved tutorialization and updated UI/interface for console play.
- Slightly sped up battle system (so it doesn't feel too slow)
Kind of a silly idea, but I'd pay good money to be able to continue experiencing this game even after its done and the idea of being able to share FFXI's story telling (some of the best in the entire FF catalog in my opinion) with my friends who are opposed to MMO's is enough to make me 100% sure I'd buy multiple copies of this to pass around.
