Shenmue kickstarter is already passed the $600K of $2 Mil, which is the minimal they are trying to raise.
Some of the donations is for an actual copy of the game. I'll probably get on that one, but really if they said $120 and get a DLC of Shenmue 1 and 2, I would be doing that in a heart beat.
Shenmue was certainly immersive...but it was oddly a surreal experience for me, at one point. I remember coming home from a hard day at work to play...a character...who goes off to work...in the video game LOL. >.>;; It was honestly a "WTF am I doing playing this game?" sort of realisation. :p It wasn't even a SIMS-type rabbit-hole-job where your character disappears for a while then comes back--I was sitting there trying to stack things with a forklift...was really bizarre LOL.
Was a lot of fun, though. My gf-at-the-time couldn't read Japanese so there would be segments of the (English-version) game that would tell you to go to a certain street address, and she'd be completely at a loss as to where to go LOL. She'd end up calling me at work to ask me what the characters would look like for the street numbers and addresses. :p
