Just to clarify Yakuza is not a JRPG. Long cutscenes dont make a game JRPG (unless every game made in Japan and some western stuff is JRPG). Or if you mean that Yakuza is a Japanese game where you play the role of someone. then I can agree its a JRPG.
I dont have problem with so called wrong classification since games now are more of a mix borrowing from different types. Plus there are so many labels for the games now that its hard to decipher the real meaning.
Have you played it? It is very much a JRPG. I use the cutscene delivery as a humorous example but the entire game is built as one, the usual RPG town, the sidequests, the leveling up, the random encounters. I bet you'll say you can find these things in other genres, but put them all in the same place and what you get is a JRPG.
I haven't gotten around to playing it yet, but from what I've seem The Last Story has a lot of those same elements, and with its anime aesthetic it was immediately called a JRPG.
I'm sorry, I thought there might have been a genre I missed, like those escape the room games that I only found out about recently.
I played Sherlock Holmes vs Jack the Ripper, I did enjoy the game asking me to make the conclusions about the murderer at the end of each chapter, I'm currently playing The Awakened. As for straightforward, I did enjoy Gemini Rue and the way I could just shoot locks instead of looking for makeshift keys, etc.
I vividly remember playing The Shivah, also from WadjetEye games, most of it was pretty easy but deducing the password to a computer and how to defeat the final boss were the most satisfying things in the game, as with most adventure games for me, because indeed there were no physical puzzle being presented, it was just a matter of working things out im my head.
