Finished Shenmue 1, and i gotta say... its a fucking terrible game. Boring ass story, boring game mechanics, horrible combat system, bad audio, forced time pacing, everything. Couldn't really recommend anyone play. I get why people put it as an amazing game, for something released in 1999 on a dreamcast its an insane engine and the things they accomplish in game are stunning for that period. It still sucks though for any modern gamer. If you loved it as a kid then for sure you should replay for nostalgia, but for everyone else Yakuza is an infinitely better choice that is a similar game but does everything better.
The port is also really buggy unfortunately, it crashed 4 times on me and at one point I had to flip my LT and RT buttons because it wouldn't let my character run anymore (known, widespread bug). If you don't skip the credits at the end you can't get a save prompt to create a 100% game finish save (to import into S2). Just tons and tons and tons of bugs like that.
I just got Yakuza 2 yesterday and after an hour I'm 100% immersed and into it, whereas I'd rather watch The Last Jedi again than play more shenmue
