Here's some comments after playing the first level:
This is complete FF:Tactics to the card game. Don't think you'll get instant retribution after playing two cards. It doesn't. This is a more drawn-out strategy game than the Duel Monsters game is. If you're bored because you're waiting to get a movement crest (multiple if there's a halved-move spell in the dimension), this isn't for you.
Also, your monsters' effects in DM aren't in DDM. No insta-death after a Man-Eater Bug is attacked. No free magic card after Magician of Faith is flipped. There are +/- effects for some monsters, and the Rock/Paper/Scissors etc. rule is also in effect (Beast over Warrior over Spellcaster -- I know it's wrong.. but to make the point).
Oh -- did I mention that you can't save until you lose or win a tournament? Yup. Be prepared to win four games through until you can save.
EDIT: Forgot to mention that DDM does include characters from the manga, so if you see some new characters, it's because they're from the old-school days, and not the 4Kids English version. That is, unless they decide to pull a Food Network and go back and show early episodes.
Graphics are ehh. Music/SFX are ehh. I'd say 2.5 out of 5 for me.
