Mario & Luigi: Partners in Time
- Luigi is the sole title character in 3 LPs an 1 Collab: Super Luigi Galaxy, Luigi's Mansion, Luigi's Mansion: Dark Moon, and New Super Luigi U.
- Two of them are Luigi-centric remakes of Mario games; the other two are games made specifically for Luigi.
- Luigi was the last plumber-type character to have been played as in an official TRG Mario Party LP. This happened in Mario Party 7 when Tim played as Luigi in Solo Mode, because there was already an account made that used Yoshi. All other 5 of the original six had been controlled by a human player before. (Jon was initially Mario before switching to Waluigi, Tim normally plays as Yoshi, Emile was initially DK before a forced switch, and both Wario and Peach have seen all three members play as them in solo-oriented modes (Wario in both 1 and 2, Peach in 6).
- Emile played as Luigi-costume Yoshi in Yoshi's Woolly World – Episode 8: Walk the Chomp to Unwind.
