With a graphical creation interface straight out of Mario Paint, and a music studio that would make the KORG DS-10 a tad jealous, this game creation tool isn't just good by itself; it's also an excellent introduction to the expansive world of game design. Of course, people who like WarioWare (such as myself) will love it too. The very idea of making your own microgames like Wario and company has appeared in forums all over the Internet. I'm not kidding. So when this game was announced, I was absolutely ecstatic, and when it finally came here, WarioWare DIY definitely lived up to my expectations. The (relatively) simple creation system is easy to master for people who know about game development, and these are the people who will probably breeze through the tutorials. However, the inexperienced should definitely pay attention to them; the Common Sense reviewer's "like learning Photoshop" analogy is correct! (However, those who want their games to involve the DS' buttons will be disappointed; the stylus is required for every input.) But making games is only part of the fun. The pre-loaded games by Wario et al. are just as good as any WarioWare game, and playing through them can give you more images and music to work with and put in games (a plus). The online component is also well-thought out, and the contests are a bit like some of the Wii Channels (Check Mii Out comes to mind). Speaking of the Wii, there's a sequel/complementary game to WWDIY called Showcase, which is an $8 downloadable Wii title. It's good as a standalone WarioWare (if a little flat), but there are many features that make it more than that for people who own this game. For one thing, you can import any game/comic/piece of music on Showcase into DIY (and vice versa). Also, the online component is even better on the Wii (as it's always connected to the internet). But I haven't even scratched the surface, as WWDIY isn't just about game-making. The comic and music creation tools are also awesome. And I haven't even began to describe all the tools available to you: sprites from old 8-bit video games, a composer that can automatically create the perfect music for your game, a LOT of sound effects, pre-made art (for comics), and stamps...need I go on? On the content side of things, mild violence and a bit of crude humor are the only things to worry about. But there's always the potential that the content of your child/teen's comic or game can be offensive. Still, Nintendo thwarts this by screening the content of each game (like Apple and the iPhone/iPad App Store). Good move, I think. Overall, I must say this again: if you own a DS and want to make games, comics, or music, GET THIS GAME.
