ApexProcyon: I have waited 18~ years to play Shenmue, I'm ready to be sorely disappointed by all the hype that has been built up since the late 90's.
I should have bought a Dreamcast back then I guess, great library of games despite short lifespan.
I've played both when they were originally released. 1 on the Dreamcast, and 2 when it came to Original Xbox.
Alot of Shenmue 1 is chasing leads to the plot, don't expect a huge amount of martial arts action. Shenmue 2 on the other hand has alot more action and is the better game imo. I think 1 got a bit criticized for not having much action so they corrected that in 2 by re-balancing the action to plot ratio. That's not to say Shenmue 1 is a bad game, in fact it's good, just don't go into 1 expecting to get into fights right off the bat.
I think the best way to describe the Shenmue series would be martial arts action meets old school point and click adventure game, just without a mouse pointer lol. Quite an immersive world with various destractions from the plot too as described in earlier posts.
