I see what you mean; and yes Fallout's game did seem robust.
I don't get much comments either, but I don't really expect it.
For one there is only 20 or so people on the forum at a given time, and many of them are lounging or in the FPSC / AppGame Kit boards.
Two, your own vision is way more clearer to yourself than it is to people who can only see videos and screenshots. They will look at things at face value, while you are looking at the potential; you see what comes next, they just see the screenshot.
Three, it takes knowledge of the field to know what to say and what not to say in a WIP; some guys don't really know how to make a reply to a WIP, it can be quite intimidating for them because they do not want to sound stupid saying something like 'Uh, yeah that is really good you know'; "why"; 'umm i don't know...'
You won't get many comments at first, but when you do finish it, you might start wishing you had less comments to read through.
Like I said, I don't get much comments but I don't focus on that; I look at the webtraffic and analytics reports; it tells a different story; it shows what people like and why. OK, you don't have a website, but you can see by your post view count that there is interest; keep an eye on it daily, do you know what day of the week is the busiest? Not all interested ones will comment straight away; some of my commentors didn't post for months. I didn't post on the TGC website for years after purchasing DBPRO.
I can see how much work you've done in the first 30 seconds of the video, just buy looking at the joints and the fluid and the seamless tile; but others can't really see what goes into it. Just like Steven Spielberg said, people don't care what goes into it, they care about what they get out of it; early in development people won't have much to say.
I have been replying to Fallouts messages about Carnage. He feels that it was too early for Kick Starter; personally I agree, it was just too early, not enough exposure. KS is not quite as much of a marketing tool as they make it out to be.
Personally I am making a game I want to play, so KS is irrelevant to me; I just want to play my game; I am playing it now; my goal is to entertain myself to 20 hours of it per week; if I can easily play 20 hours, I expect others to want to play 10.
One word about your graphics; I think you should use some royalty free creative commons tilework if your not into the graphic design field; currently the visuals distract the audience away from its potential by looking a bit flat. If you are into graphic design then try to work from real references; forget using other games, nothing beats the reality as a reference. My reference library has few games; lots of real photos.
