Is Yakuza for me?

[umegames]

Been thinking about getting into the Yakuza series, and I'm just looking for some insight from you all. 

Once was told it's in likeness to shenmue, which i did truly enjoy on the Dreamcast back in the day, is that an accurate comparison? 

Also, if i do jump in, do i need to start with 0 or can i do 1 first? asking because 1 currently sales for $16 with GCU @ bestbuy, while 0 is still $40.
