Good for 13 hours. Then it's done.
THE GOOD
1)Very fun battle system.
2)Capturing monsters and leveling them up? Not entirely new, but better than fighting alone.
3)Weee drawing spells. Highlight of the game.
4)New game plus that allows you to keep your items and stats, and present higher level enemies.
5)3 paths to the story.
THE BAD
1)After you've done the 3 paths, it's over. Not much to keep you playing. At all.
2)More trio rune combinations would have been fun.
3)There may be 3 paths, but they all lead to the same fights.
4)Not many sidequests.
5)Keeping up your spell levels can be very high-maintenance.
6)Story is very bland. Bad dramatics. Predictable.
7)WTF is that last boss fight. Too easy.
8)Endings are very bitter-sweet.
9)Level maxes are pretty low.
10)Not the best graphics, even for DS.
FINAL WORD
Lost magic is a great game to RENT. After you've played 13 hours, you never feel like touching it again. It's just too much of the same stuff. But for that 13 hours, it's a hella fun.
