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.
Disappointing Last Level: That stupid dream stairway that comes between the second-to-last final boss and the final boss. Fortunately, with properly leveled up weapons, it shouldn't take long. Still, it stalls what was up until then a very intense climax in the game.
To be clear, the stairway itself isn't the problem, as it's atmospheric and awe-inspiring. The problem is that it consists of a handful-of mini-boss fights separated out by huuuuge stretches of featureless walkway. As in, maybe two completely dull minutes of running uphill between fights.
Goddamned Bats: The literal goddamned bats...at least when you are required to use your melee weapon on them or Item attacks.
Les Yay: In Chronicle, if Monica talks to Claire before she joins the party, Claire sort of crushes on her.
The game adds more freedom to the city building (you can make tons of items to decorate the houses or the areas around them, you can move in more people even after getting 100% completion if you want, etc.), than its predecessor, making it fun to play for the heck of it.
Fishing activities are also revampled. You can level up your fishing poles, and there's a fishing contest that gives prizes for the largest fish, and an aquarium where you can feed and breed your fish to prepare them for the Fish Race.
The golf-like mini-game (Spheda) can net you some awesome prizes on some floors.
Medal collecting, photography, and Item Crafting are all very fun and can be very time consuming if you sink in.
Surprisingly Improved Sequel: Graphics were improved, voice acting was added, weapons no longer permanently disappear, the city building mechanics were given more depth and tons of addictive minigames were included.
