They are making “complete” games with no early access period and no DLC with shockingly high production values for the budget. And people are ignoring them until there is a massive sale

I can think of several other variables that may be necessary for success that aren't being tested in that statement. Like, is it a setting that resonates with people? Yes, I want more Max Payne, but not so much with vampires in it. Then when you find a game that gets acclaim and the audience is there for it, this is a good time to sequel that game, because now there's brand recognition on the game people like, and they'll be more willing to spend full price on a game where they're confident in what they're getting.
