Basically, I would say it is worth getting but don’t be surprised if you use it more as a pastime when you have like a half hour to kill rather than something you play for hours on end.
When I first got it, I really didn’t know much about this odd battling style that it had. But, once I started playing it, and experienced my first battle, I was immediately hooked. You have to use strategy in your battles, so that you position yourself in the correct spots to go in for the kill. I love how the battle system is much like a board game, where the players take turns moving towards each other (chess). And, when two players meet, the dominant one will win. I just love this aspect of the game.
Another thing I liked was the duration of it. There are over 300 missions, and it should easily take you 100 hours if you go for just about all of them. I like how you can repeat some missions over and over again, as to get more weapons, money, and/or experience.
Overall, I just really think this game is excellent.
My other problem, is the lack of equipment early. I’m the kind of guy who likes to do every side mission before going onto a storyline mission. Now my characters have learned nearly every abilitiy available to the jobs I want them as in the future, except for the really good ones that make the jobs good (ie Meltdown, Two Swords, etc.). And I can’t get the weapons to learn them yet, so I basically just waste exp =\.
The other problem is Mythril Weapons for using Combo, and the fact that some people can get unlucky and not find any of them.
