You want to know what all those lists (including the one being discussed) have in common? They were all made by somebody who just shut the hell up and made a game. It's the same in pretty much every walk of life. There are people who make games (or who make movies, or who write novels) and then there are people that sit around on the Internet all day, browsing reddit, checking gd.net, looking up 1001 inspirational articles to help them get all fired up and thinking "f yeah, I'm gonna make a game and these guys that made this list totally told me that it's possible!" and pretty much doing everything except making a game.
You don't need some list maker to tell you it's totally possible for you, yes you, to make a game.
I have this sneaking feeling that somewhere along the way, people have gotten lost. Once upon a time, just getting together the right tools to make a game was a challenging proposition. At some point, though, compilers and art tools became readily available for free, APIs sprang up that made it a veritable dream to make games, and yet it didn't seem to actually get easier to make a game for a lot of people. I think the problem is now that there is such a glut of information and time-wasting. You get on the net with the intention of making a game, and you end up instead reading a list of 15 awesome things you just totally have to not fucking give a shit about, because you are not here to read about that stupid crap, you're here to make a game. So download your tools, shut your browser, and make a game.
I know, I know, I need to practice what I preach.
Never wiser words spoken.. I'm guilty of this also, spend less time thinking about the subject and more time learning / doing.
