Just because Shenmue is littered with QTE doesn't make the gamplay totally different. Like I said Yakuza relies a lot more on fighting (which is also a big part in Shenmue) while you do a lot more investigating in Shenmue. "The closest you can get" (to quote myself) doesn't mean it's the same game with different characters it literally means it's the closest you can get.
Again, saying Shenmue is like Yakuza is misleading because the two series play nothing like one another. Yakuza's fighting system is far more simplistic, and combat is a
much bigger gameplay focus. Shenmue is largely about talking to people, observing the world and the little details in it, watching people go about their daily routines, stuff like that. Hours can go by without any combat. In contrast, in Yakuza there aren't really any details to notice. You just wander around the crowded-but-barren city streets (none of the NPCs are interesting or differentiated from one another) being dragged into random battles. In Shenmue, the world exists to be explored and appreciated, whereas in Yakuza there's almost no real "exploration." Outside of its mostly skin-deep "open world" trappings, the game world is much more utilitarian, existing mainly to shuttle you from one plot point to another, tossing some items, experience points, and fetch quests at you along the way. (And don't get me wrong. I LOVE Yakuza.)
It's easy to say, "Well you investigate stuff in this game, and in this other game you investigate stuff too, so the games are alike!" But you investigate things in plenty of games, and almost all games revolve around combat.
I mean, it's obvious
why people compare the two series to one another, but aside from largely superficial similarities, they're really nothing alike. Telling someone who has never played one of the series (or either) that they are similar is misleading.
And it's not like I made that up myself. Anyone I know who played both and people all over the internet seem to agree. Just type "Yakuza spiritual successor" in google and be amazed.
Oh I know you didn't make it up. I see the same nonsense repeated over and over on GAF. But a lot of people thinking something doesn't make it true. Yakuza is not really anything like Shenmue.
