Great ideas were involved with this one. A few adjustment could have been considered though...
In the other additions to the "Secret of Mana" serise you always had a party of three that you could switch between and mold to your liking, these characters added depth to the story pluss, if you wanted too you could play with two other freinds on your team. In this version however, the only character that sticks with you throughout the stories is a pet you can hatch at the monster corral and it is't even playable. Other characters are playable by your freinds, but they come and go so often that your freind will get bored waiting for one to join you again. Their is a cool option to upload someone elses character an ether fight or have them join you, but it's a little acquard that they look like a clone of your character and are just as uncommentary about what is going on as you or your pet is.
However other than that, I can't think of anything else besides the lack of difficult battles that would mess with the player's experience. I would have like to struggle with the enemies a little more, but these are the only things that made it "imperfect". It still was a wonderful buy for anyone who likes gameplay similar to "Kingdom Hearts" or "Secret of Mana". The money will make the purchase more than worth it now that it's a bargin item.
If you are an RPG fan then get this game. It's worth every penny.
