Someone saved over an FF game of mine before....i went absolutly nuclear!!!
I personally thought the sphere-grid was great......true there was some work to be done to max everyone out, but King Tonberry is there to help with that..(it's not cheating!)
The problem i had with it was that once evryone was maxed out they were all exactly the same.....unlike 9 where all characters have very unique abilities.
I was a little worried at first that they had got rid of the leveling system but due to the scope and length of the game it makes sense.....you'd probably reach LVL100 after about 50 hours (out of 300)
I cant understand why people dont like it.........
