So it's "build porn" game because you watch how someone else do it, like in regular porn, instead of doing something yourself?
It's a good question actually. I don't know why I like build vids, I just do - and evidently lots of others do too. There's a certain stage when you're getting into a game when you just can't get enough of it, of thinking about it, and build vids feed into that momentary obsession.
I guess it's capitalizing on other peoples' time investment. I mean, I spend a fair amount of time playing games, but not as much as some of these people obviously do, and they learn about things I just don't have the time to learn, so why not take advantage of that?
