I am twenty hours in, just finished Chapter 2. I did the whole damn
thing. By far the longest, and weirdest, side mission I have ever played in a game. And without knowing what the result would be ahead of time, probably the most time I've put into activities that amount to a Bronze Trophy.
It is pretty obvious at this point that going through the campaign is going to be at least twice as long as the usual 25 hours it takes me for one of these games, if only because I'm putting off less of the side missions for post game. Some of the new stuff is genuinely batshit crazy. The taxi stuff, everything in the mountain village, people sliding down a sidewalk like penguins while you deliver ramen (to a guy that couldn't be bothered to walk twenty feet to the injured deliveryman), and Snowball Deathmatch are the sort of things that only the people who make these games could come up with. At this point, I'm not going to be surprised when something finally makes me laugh harder than the diaper fetishists from Yakuza 2.
On top of the insanity and bizarre side mission mechanics, the story is really great so far, and the core game play has never been better. I had everything maxed out for Kiriyu at the end of chapter 1, and nearly accomplished the same for Saejima in chapter 2 (I'm guessing these ability caps go up in later chapters). Heat moves are still fun as hell, the essence shockwave move can send half a dozen enemies flying at once, and they finally gave a reason to visit to eateries when your health is full. Other than the inexplicable invisible barriers on streets between accessible areas of Tsukimino, the new locations are very well done. Looking forward to seeing what Sotenbori looks like in this decade.
