I'd say Wii simply for the controls (Opening drawers, touching Sailors). They'd have to port the first two, too.
But as an owner of Shenmue 1 and Shenmue 2, the games were great for their time but they've been eclipsed by other open world games. Being able to talk to everyone in a city and get a job isn't as fun/amazing as it was almost 10 years agon.
