So I'll begin with why the original Shenmue was legendary compared to the sequel Shenmue 2. I know that there are different opinions but I'll have to share mine to mabye convince you if you think 2 was better.
First of all. The environments, interactivity, just spot on. Shenmue 2 lacked this since it included much bigger areas and the metropolis of Hong Kong. I'll agree that there was more to see and explore but Shenmue 1 makes up for this since it allowed more change and difference in each and everyday. You could interact with so much in your home by realistically opening draws whilst Shenmue 2 didin't have many. You could also pet a cat in 1 so fuck yeah!
Oh, the time difference. Shenmue's time feature included days that went on fairly quickly, making one hour in game time 5 minutes in real. Shenmue 2 also had this but damn, we were able to see that we would get late arriving home or see if there was any additional stuff to do in the day. You could also train your moveset more realistically through each day, although tedious, it made you feel more engaged and was time-worthy. Shenmue 2 limited training and made moves piss easy.
That brings me to another point. You can play the game however you like, Shenmue 2 focused too much on mini games which were slightly repetetive and meaningless. Shenmue 1 included collecting and you could have a big collection in your inventory or a small one. Shenmue 2 compressed everything you had and hid them
away, with no meaning whatsoever.
Finally, the music. The FREE music in the game, especially the one when you first leave your house, it is truly unique and emotional, even till this day, sure Shenmue 2 had great music too but Shenmue 1 was much more emotional and appealing. It always changed and suited the mood you played in. I think it was better than 2.
I just wanted to express my opinion on the original Shenmue and how superior it is to 2. Don't get me wrong, Shenmue 2 is also a great game, but different.
