Lone wolf doesn't mean no contacts at all and no experience. It means doing the vast majority of the work on your own. Notch did that. But there are lessons to learn from what you say. It's important to be able to reach the community, and that doesn't just mean marketing or hoping for a good review somewhere. It can mean participating in conversations with other developers and gamers and forming bonds that lead people to be interested in what you're making. It can mean taking part in events that raise your profile like Ludum Dare, 1 Game A Month, Global Game Jam, etc. People have to know about your game to want to buy it, and often the best way for them to know about your game is for them to know about you.

I'll take your interpretation as being sound for the games industry, and those that frequent it online. After all what's considered a small production still involves the time of a dozen or three(dozen) people.

However I find difficulty labeling 'lone wolf' while surrounded by multiple communities, and communities that you've raised to an extent or another. Just from the imagery of a pack animal, that isn't one anymore. Most successful games that are 'lone wolf' are just very very social, and in the discussion it was something that hasn't been covered very well.

You have to work with/for communities, and a lot of work at that. I feel that the term gives false implications behind the meaning of lone wolf.
