Nintendo has been talking about the downloadable expansion for New Super Mario Bros. U starring Luigi in his own adventure for a while now, but it's finally time to get past the talk and focus on a release date and price. New Super Luigi U will be available as a $19.99 download on June 20. However, if you don't mind waiting and you're trying to save space on your Wii U's system memory, you can pick up the expansion as a standalone disc at retail for $29.99 on August 25. The disc even comes in a snappy green case featuring "Year of Luigi" branding.
Since Mario sits this game out, another character needs to fill his slot in the playable character roster. Enter Nabbit, one of Mario U's new additions, who cannot power-up with traditional items, but can run into enemies without taking any damage. So there's a trade-off for you. Nabbit is meant to be controlled by the less skilled Mario fan in your couch clan, giving him character invulnerability not seen since Player 2 realized that Tails was immune to harm in the traditionally single-player mode of Sonic the Hedgehog 2.
I like the idea of a retail release for Luigi U. Nintendo has been hyping this DLC as a whole new game, so if that's really true, then why not send it out to retail at a budget price? While Nintendo did announce all of this new information, one item left out of all of this is the file size of the DLC. With the limited memory available on the Wii U out of the box, it might make more sense to pay the extra $10 and pick up the disc if the downloadable version of the expansion will take up lots of space. Say, do you know what would be nice for prospective Wii U owners? A bundle made up of both Mario U and Luigi U sold at a slight discount compared to buying both separately. I could definitely go for that when the time came to pick up a Wii U.
