Of course it should outpace Bloodstained, this is SHENMUE 3 we're talking about here (Which got revealed in Sony's conference, to boot). It has way more exposure than Bloodstained ever did, and let's not forget how passionate Shenmue's fanbase is.
Plus, Shenmue 3's KS seems to be aiming way higher in terms of stretch goals. Assuming that there are two more villages aside from Baisha, then stretch goals would probably go to 7M or 8M.
No, but I wouldn't expect the non-hardcore fans to pledge anything more than the lower couple of tiers anyway. I mean... I certainly haven't backed any other projects in that way. Like, I'm not a Wasteland fanatic or Castlevania fanatic. You think anything was gonna get me to kick in $250 for Wasteland 2 or Bloodstained? Anything above the two lowest tiers is really for hardcore fans.
I don't think you have to be a hardcore fan to support a project you're interested in. A lot of people are interested in Shenmue even though they haven't played any game in the series. True that the majority of them won't pledge more than the base reward, but some would definitely want to help the project realize it's potential. The gaming community knows how expensive Shenmue was to make, and I could see an effort from many to up their pledge so that Suzuki and his team get to make a sequel worthy of the franchise.
