> Think about the skills required to create a presentable product, then think about the time you have to sink into it with no idea if you'll have any success at all.
You say these things like it isn't true of literally every creative endeavor including writing.
> But that's not where it starts. You can tell a story in a book that can be made into a movie, because they can overlap.
Many game developers of yesteryear took their inspiration from tabletop RPGs, board games, sports, and just regular real world activities that looked interesting. There are places to start other than diving in a making a game... and yet lots of people do, because it has a low barrier to entry.
> You can't write a book and then turn it into a game, because the most important aspect of a game - gameplay - isn't something that a book can handle in any way.
A strange thing to say considering how many games are incredibly linear stories with almost no gameplay whatsoever. Also strange considering how many books simply don't translate to film very well. Go on, write a screenplay for Gravity's Rainbow, I dare you.
But seriously, there are lots of ways to learn game design without ever touching electronics. Human beings have been designing all sorts of games since they've had enough free time to play games. A lot of those ideas can become video games.
