I've not yet given myself the opportunity to get into WarioWare, which is curious considering I'm sickeningly addicted to Rhythm Heaven. But that's another story. The resently released "Made In Ore," or WarioWare: Myself! as it will be known to us, allows players to make their own minigames. So it's unsurprising that people would use it to represent their favorite franchises. Well, as you've probably already seen from above, we already have one created by Tarbosan that features Rockman EXE, where the right timing is needed to blast the moving virus. Pretty simplistic, and unfortunately the video has no sound. However, you can check out the making of the game on his blog. Pretty novel idea.
A lot of neat Mega Man minigames could come about with this, as I've read you will be able to upload and share your creations. I do have to wonder, though, how tightly monitored the network will be in response to copyrighted materials. It would seem like a waste if people can't share games with the franchises they love.
