According to a recent Tweet from Nintendo Europe, Wii U owners in Europe will be able to get a free download of the N64 classic Mario Tennis if they purchase the series’ latest iteration — Mario Tennis: Ultra Smash — via the eShop by December 17th. While the game has been receiving a lukewarm reception from fans, the two-for-one deal is a fantastic offer for those still on the fence.

On the other side, Nintendo has yet to announce where the promotion will apply to those buying from the eShop in other regions. Mario Tennis: Ultra Smash releases today, November 20th, in North America and Europe.
