-The upcoming FF MMO will probably have a combat system like FF XI or XII where commands are entered and then executed according to character stats
-There seem to be two final fantasy 13s because one is the main final fantasy and there is a more action RPG spinoff being made called final fantasy 13 VERSUS
- The different numbered entries in the final fantasy series have completely separate stories from each other so you should have no problems there
- It depends what you are looking for, but FF 13 versus is a PS3 exclusive and the battle systems and feel of the games will be different so which one is better will depend on taste most likely
Some of this may be wrong, but it is close enough
