They roll balls of colorful paint around canvasses, look cute, then eat graham crackers.
Now aside from wishing I was a kid again, seeing these bright and beautiful pieces of work made me think of a fun game idea.
There hasn't been enough good "art" games in the history of video gaming. I'm a believer that video games can be art, but that is a different conversation. We're talking about using your virtual cursor to create. In fact, the most recent successful incarnations that I can think of in this limited genre are Colors! and Inchworm for the DS, both homebrew digital painting application.
And considering the touch-screen capabilities, it is surprising we aren't seeing more on the handheld market.
But the most memorable game in this area hands down is Mario Paint. Borrowing the immortal Mario name but scarcely having anything to do with it, Mario Paint rests in history as one of the only original IPs that Nintendo hasn't dug up.
Question... why not? Looking at the Wii's hardware, an update to one of the Super Nintendo's most beloved games is more than within reason. Let's start with the logistics of a Nintendo decision to bring the game back.
Infamously, Nintendo is working to ride the line between "casual" and "core" games. Looking at their first-party software library, they are doing a pretty good job. There's a good mix of games, and some do a good job to allow players to mix up their core gaming with their casual. But no game would appease both sides as well as a new Mario Paint. This is especially considering the original game still has a very strong showing online, with impressive tunes being made using Mario Paint's music maker, like the immortal "Still Alive" song from Portal.
It would appear on the Wii for about $10-15 (depending on the features involved), and using a Nunchuk could truly make virtual art fun! And the possible control schemes in multiple modes using the Remote and Nunchuk make this game petition-worthy. We could see modes like:
Simple, by-numbers painting - If you are one of the 9 people that have played around with the Photo Channel, you'll agree that the Wii Remote has potential for drawing mustaches on a picture of your friend. And even though the Photo Channel can be considered poorly executed, the idea of being able to use the wiimote to doodle, cut/copy/paste, and other basic MS Paint actions has got me thinking. If even more options and finer-tuned controls were added to this idea, couldn't this make an enjoyable Wii Ware game on its own?
Music Composer - This sold Mario Paint. Being able to create your favorite Nintendo tunes on your SNES was wicked-sweet. With Wii Music on the way, some would argue this feature useless. Since, as of now, Wii Music will feature a mode that is nothing like the music creator in Mario Paint, it would be a great addition to the bundle.
Gnat Attack - Clicking on the coffee mug let you play one of my favorite mini-games ever. If the magic of point-and-click wasp killing could be translated in a classic, fun way to the Wii, this game would be an instant hit.
Movie/animation studio - Mario Paint gave us the ability to create mini-movies on the Super Nintendo. They even provided Super Mario World characters to create the feeling that we are an animation studio director. Of course, it was very limited at the time. With much more power in the Wii's hardware, this is another mini-genre that would have a perfect fit with Nintendo. Could we make Link run up and kiss Peach as Mario shakes his fist in anger in our own Nintendo-themed soap opera?

This last idea isn't very far off from seeing birth. With the development of Wii Spray on the way, we could possibly see quality virtual graffiti in this console generation. But a Nintendo-developed one would not only use less hardware like a pc and projector screen, but would come with the quality precision that Nintendo is known for. Even using the IR sensor itself would open up enough possibilities that it could make a sufficient downloadable title. But having a free-paint mode that lets your hands truly do the work could reboot a genre long lost.
There are plenty of games that developers should be rolling out with, that only gamers seem to have the vision for. Sure, it is not as if I am the only one to think of it, but googling "Mario Paint Wii" sure doesn't come up with many results, and they revolve around the time the Wii was first coming out. If there is a game that comes to your mind that should see the light of day, feel free to keep the roundtable going on it.
