Uh, well, i don't know about that. I mean, keep in mind that Ranma is way more comedic and a bit less grounded than something like Shenmue, with a ton of wacky characters, silly plotlines and some romantic stuff sprinkled here and there. I don't know exactly why you despise anime (i don't care about most of the post-early 2000s' ones too, honestly), but i guess you have to like japanese-flavoured comedy in order to enjoy it.
Personally, i really love it, all the characters are really likeable and i think it's actually pretty funny. In particular i love the anime version, it has a lot of that late 80s'/early 90s' charm (ie: no cheap cg bullshit shoved in it, no horrible, hyper-bright modern digital coloration, classy character design, fantastic syntethic music, etc), but i don't know how much of it can be enjoyed if watched today for the first time ever.
I also own a lot of the manga's books, and i like it too and it's probably funnier, but honestly even though i love Rumiko Takashi and most of her things i think it's very poorly drawn, and of course the fight scenes are better in motion anyway. I also enjoy the slower, more atmospheric pace.
The animated version is mostly faithful, with some occasional, notable differences, and in most cases i think it vastly wins over the manga one, but that's my opinion.
Anyway, i didn't want to shill Ranma here, it's just that i noticed a lot of coincidences with Shenmue
