Creative and fun
This game is has one of the most (or the most) impressive, use of the Nintendo DS's touch screen. The game play is smooth and easy to use, and there are secret actions most of the MGs can preform (like breaking some of the control panel to reveal a hidden button). There are a verity of different Marionette Gears to play as and a few different types of missions. This game is one of the best on the DS and a must buy for giant robot fans, and there are guides on GameFAQs for people who cannot read Japanese (like me).

A Pretty Good Game
If you ever played Robot Alchemic Drive for the ps2, Choushoujuu Mecha MG is R.A.D. in a hand-held version, minus the human pilot on the ground. Choushoujuu is stylus-intensive rock-moving, mecha-battling action. The game has hundreds of missions (with 5 difficulties for each earning you more money the harder it gets) and mecha to acquire. Some of the missions are tedious but the action is good though a bit hard to figure out sometimes when you don't know any Japanese or very little. Try to find translations at gamebrink or gamefaqs if you can. Definitely worth the price tag.

Heavy use of touch screen = Fun!
It's a pretty cool game with a LOT of missions, although some are tedious and short.

What I love the most is it's heavy use of the touch screen :)

If you can get it, buy it!

Yup, it's awesome
Wacky, bizarre mech combat from the creators of "Earth Defense Force." If this game looks remotely interesting to you, pick it up. One of the most fun games on DS.

Great game!
Even with no knowledge of the Japanese language, this game is still one of the very best for DS. Tons of robots to choose from, over 400 + missions to complete and enough replay to make this game take up a permanent home in your DS. People go wild for the Jump and Bleach games...be the first to play this. It'll be the next big import...get in on the ground floor!
