These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Scrappy Level: Shu Shirakawa's storyline is rather hard to begin, with most allies being optional and no battleship present for resupply purposes. However, the worst is definitely the stage that pits the player against hordes of strong mooks...without Shu. Even if you use a cheat to bring the Neo Granzon, it won't make it any easier.
