As great as the game is on the whole, there are definitely moments where players will feel their patience being tested, and during extended play sessions parts of The Fractured but Whole do seem like a bit of a slog.
For instance, the majority of the game's missions are effectively fetch quests, requiring you to meet a character, watch a quick cut-scene, then go somewhere else, grab an item, fight someone, and rinse and repeat.
It doesn't help that the fast travel system is fairly inadequate and walking around town can be awkward due to numerous obstacles blocking your direct route (earlier in the game, at least).
Furthermore, mini-games and animated sequences during battle wear our their welcome later on, especially as boss fights can drag on for 10-15 minutes sometimes.
And of course, the reliance on fart jokes will probably end up seeming a little overdone to some players.
