Road Redemption is a Road Rash inspired game coming to the Wii U, PC, Mac, and Linux if it gets funded. If you're really interested in this game, please do them a favor and support their game by donating to their kickstarter! After all, we could use more Wii U games!
Here is a link to the kickstarter with a lot of info of the game and some gameplay footage:
I found achievements to be boring now. All games need are just unlockables that require you to do certain tasks, not raise a number score that means nothing on your profile. Not signing.
