Spoiler I liked the parts that weren't in the games. Where the anime tries to cover what we've seen in the game it's clearly lacking because it's rushing through the story and not going into any real depth, leaving things just happening and then moving on ("Oh that guy who's been kicking my ass the last 12 times we met? Yeah I just finished him off in 30 seconds."). The Wude section was well-paced; we got a focus on Ryo's personal development alongside the story development (where the game treats them separately) and this massively improved the flow of things. We even got some cameos from Eileen and Izumi, although no Duck Racing unfortunately. The rest of it seems to have been a case of "well we need to get 100 hours of content into 5 hours of anime... also we're going to make a bunch of new stuff too" and it's just things happening as a result. I still don't know what the purpose was to making Mark, Goro, and Mai involved in the Terry showdown, it seemed like a change just for change's sake. Also, Shenmue III version of the cave scene, guess that retcon's staying.
