I would ultimately have no issue with it, but Shenmue's appeal goes beyond its story. As a game, an active form of media as opposed to passive, you're allowed to freely interact with its world and people, which a lot of games have not managed to capture to the same depth Shenmue has. While many open world games today are as vast as an ocean, they're as deep as a pond. While Shenmue is as vast as a lake, it's as deep as the ocean. I feel with an anime, while I do anticipate it will be good, will never capture the magic of what the game sets out to do "as a game." But if I had no choice but with an anime, I'll gladly take it as long as it keeps the music and voice actors as well.
