Same, I just finished the game 31 hours in all. Did everything, got everything. Loved it.
It was a real joy to play this game, but my biggest complaint would be that the main plot came and went too quickly. It was a lot like Mafia II in that regard, outstanding atmosphere, decent enough plot, great characters, really solid gameplay, but the overall progression felt rushed and severely underdeveloped.
I kept wanting to see more of the life. The game never really gave me a sense of what the life of a Triad member was like. Wei progressed through the ranks far too quickly, the entire main plot felt extremely bullet points only, just like Mafia II. I wish there was another 10 hours to the main campaign to really flesh out Wei's rise in the Triad and to develop the supporting cast. Other than Jackie, which wasnt even that well developed, Wei's relationship with everyone was almost non-existent. More police work would have been great too, a lot of the "tools" Wei had were barely ever used, like the security cameras, whats the point of hacking all of them when only like 1/3 were actually used, and even then only for the drug bust sidequest.
I would love to see a sequel where they really beefed up the game, providing a super detailed and well developed journey from the bottom ranks to Triad glory.
