So what if it didn't change much from the GBA version that's what makes this game great!
The good things about this game are that the new plot is very interesting and the ending is a pretty good plot twist,if you have any of the old GBA games you'll be able to unlock a amazing weapon,it's a pretty long game and there's lots more to do after you beat the game,boss battles are great,the battle cards are more powerfull,the BrotherBand system is a great addition to the game,on-line play is another grreat addition,and it has great little use's for the touch screen weither its being use to enter waveholes or transers or doing little things to get to the boss battles.
Thankfully there are alot less bads then goods.
The only bad parts are that the level system in a liitle on the illogical side,you level up based on you HP level not your actualy skill (enemies deleated,average cards used per battle,things like that),jobs can involve lots of runing between the real word and the wave roads which will indeed get annoying,and the customizer is now gone only to be replaced by weapons for Mega.
Overall this game will be great for anybody looking for a great roleplaying game for DS.
