That is why the only real hope of the developers is to change X. And that is possible. There are hundreds of thousands of 12-year-olds who are obsessed with Minecraft. (Seriously: last week when my son visited a new school wearing a Minecraft shirt, something like 60% of the male middleschoolers go out of their way to say something about it to him, and several teachers mentioned how obsessed they were.) That market didn't exist before Minecraft.
In a similar vein, I spend a certain number of hours per week watching shows on Netflix, and I am certain that I could be persuaded to spend a big chunk of that time playing a game (for which I would gladly pay money). But it isn't one of my habits -- someone would need to find the sort of game I would enjoy and manage to let me know about it.
Here are some hints: since I am not your normal market I don't own the latest console nor do I own a fancy controller (but I CAN run Steam). I am not that excited about first-person-shoot-em-ups (if I were then I would already have gotten involved), but I might be interested in something more strategic. I am not willing to pay much up-front (since I don't know for sure if I'll really be into doing this) but I would be willing to spend money once I know that I like it, so long as I don't feel like I am being cheated (mandatory in-game payments or play-to-win often leaves me feeling that way). And most important of all, I do not read the indy gaming press or attend indy gaming conferences (since I am a NOT the existing demographic), so you need to reach me some other way -- probably through my friends, using some form of viral marketing.
The market for independent video games is small, but the market for entertainment is astonishingly large. (Plus, maybe your game can be something ELSE... educational perhaps?) The route to profit is to find a new (bigger) niche.
