Nintendo's got two new WarioWare games to release on 30th April, one for DS and one for Wii. What's more, they'll work together.
For DS there is WarioWare: Do It Yourself, and as the subtitle suggests the key feature will be creating and sharing your own micro-games using the Wi-Fi connection. Swapping should be a snappy process, as each micro-game will only be around 10 seconds long.
Nintendo will hold Design Challenge contests to keep the community active, and the tools have thorough tutorials to get you started.
If you don't fancy all that, though, you can tackle the 90 micro-games already on the cartridge. WarioWare: DIY has a feature where you can create four-panel black and white comics or craft your own songs using one of 90 samples as guides.
The WiiWare game sounds very similar: WarioWare: Do It Yourself - Showcase. This packs 70 micro-games and can play micro-games created on DS.
There's a multiplayer mode for four people to unlock as well as a mini-game based on Balloon Fight, where you collect musical notes to achieve a high score.
