Are there any parts/side quests in the game that you simply cannot stand?
I can name quite a few:
The process of getting Doomtrain
The Dollet exam
The D-District Prison
Galbadia Missile Base
Going through the Deling sewers as the "Gateway Team"
The Basketball Court scene at Trabia Garden
Destroying the Propagators
Laguna dreams (However on my 4th and current playthrough, they were not as bad)
Most of these I dislike because they take so long and aren't important to the story.
