Was going to do a very detailed response, but felt like I was orbiting around the point, so rewriting for another try.
The issue is, if I don't look at this as an Arcen fan, but look at it as a complete outsider, there's a set of things which one might call 'expectations' and a set of things which one might call 'features'. Things like 'the UI is good' or 'there's a good tutorial' or even '3D graphics' aren't features, they're expectations. They're things which if you tell me are absent, I'll have a negative impression, but if you tell me they're present I'm going to think 'so what, every game has to have that, what makes this different?'.
If I'm just checking something out at Steam store, I might not need anything more than having expectations be met for a professional, polished game (if I'm bored, if its on sale, if its a genre I like, etc). But if its a Kickstarter, that's a developer saying 'here's a vision, but I can't afford to make it - this vision will not exist unless I receive support'. If you show me a lot of stuff which meets my expectations, but no revolutionary or radical or risky new features or promises of insights and wonders, well, the natural thing for me to think is 'there's going to be 10 other games like this, probably out on Steam before this KS even finishes, so why should I go out of my way to support this one?'
As an Arcen fan, I'm more likely to think 'well, I know the devs, I know the product line, I trust them to be creative and interesting'. But I don't think that's the right point of view to be taking for aiming a Kickstarter campaign.
