A Solid DS RPG with lots of Slime Goodness.
There's a ton of these to do to collect all the slimes and on top of that after retreiving a certain slime you can enter a tank battle arena which features another 15 or so tank battles. The story isn't very deep, so hopefully you aren't looking for that. It's got a bunch of old Dragon Quest references and even some Final Fantasy ones so thats fun if you catch them. The sound is pretty nice. Just what you'd expect from a Dragon Quest games, features lots of the classical sounds actually. All in all I'd say it's a fun experience if you're looking for something to occupy some time (you know, since FF3 got pushed back TWO MONTHS.) It's got a lot of good material so check it out and enjoy.
