Luigi's Mansion 3 is undoubtedly the Nintendo Switch's latest killer app and is worth any Switch owner's time. However, for how great the content of Luigi's Mansion 3 is, the game fundamentally falls short due to untapped potential in certain features that could have easily fit into the game.

Luigi's Mansion 3's gameplay mechanics are simple, fun, and used cleverly throughout the game. However, it seems there was  a missed opportunity when it comes to upgrades and abilities. On a basic level, Luigi can use the Poltergust G-00 to battle a variety of ghosts, interact with objects, solve puzzles, and move large items with a plunger that can be fired at them and later latched onto with the Poltergust G-00. These are solid mechanics and work quite well. However, it seems like developer Next Level Games could have added an upgrade system that, for example, would have boosted the suction power of the Poltergust G-00 perhaps using a tier system.

Or, the Poltergust G-00 frankly could have stood to get new abilities along the way. Next Level Games may have missed the opportunity to give the game an element of verticality. In other words, it would have been interesting to see the Poltergust G-00 sport a rappeling function, allowing Luigi to climb both up and down different levels within hotel floors.

All of this could have been handled through the game's strange monetary system. From traditional Mario coins to paper currency absent since the first Luigi's Mansion to a variety of jewels, Luigi ends up being one rich plumber after the game's over, as the money is never used in the first place. An "abilities and upgrades" system could have been facilitated through the game's underutilized currency.

Luigi's Mansion 3 still stands as one of the Switch's highlights, but there are some flaws that hinder its further potential. One of these most prominent involves a lack of features that could have diversified Luigi's experience within the haunted hotel, though it's never too late for Nintendo to add an update or DLC pack.
