LEGO's collaboration with Nintendo has been an unequivocal success for both companies. Following the debut of the LEGO Super Mario set, more expansions themed around Nintendo's plumber mascot and his Mushroom Kingdom adventures have been revealed and released. Reports even stated that it's one of LEGO's most profitable themed sets. So it only made sense to introduce Mario's brother Luigi as well.

A LEGO Luigi figure was accidentally leaked before it was officially announced, with it boasting all the same features as the LEGO Mario figure (sound effects, an LCD screen etc.) and coming with a whole new course as well. Not only that but, with Luigi perhaps being the epitome of the Player 2 character, LEGO has explained that his arrival means friends and family can play through the different courses in co-op.

In a manner somewhat reminiscent of the co-op seen in the New Super Mario Bros. games, a new YouTube trailer demonstrates how fans can each use the Mario and Luigi figures and work together to complete the courses. According to the video description, since the two figures can interact and react to each other, two LEGO enthusiasts can make the characters perform in-sync actions like walking, flipping, and jumping, which will earn them extra coins. LEGO writes that this new way of playing enables people to interact as a team.

While the trailer appears to focus more on the cooperative side of things, the description does add that these new two-player adventures allow fans to compete against each other, again not too dissimilar to how the New Super Mario Bros. games worked. In those games, players all shared the same goal of reaching the end of the level, but could also interfere with each other to earn the most points.

The end also shows off one of the new LEGO Super Mario sets coming out: one made to resemble one of Bowser's airships, which first appeared in Super Mario Bros. 3 and have made regular appearances throughout the franchise since then. The set also comes with a figure of Kamek, one of Bowser's loyal henchmen.

Given the popularity of the LEGO Mario sets, it would make sense for other Nintendo properties to receive similar treatment, such as The Legend of Zelda and Metroid. It's possible, though, that Nintendo will want to focus on the Mario series for the time being. Aside from it arguably being the company's most recognized franchise, some of its characters have yet to receive LEGO figures of their own, with perhaps the most glaring omission so far being Princess Peach.
