Some released this month have already 30-50 reviews, and by experience I know they've already made a LOT of money
also checking the Patreon pages of some of them, they make just from that more than what I make with all my revenue sources combined 
Of course it's not easy, doing that 3d art takes a lot of work and also very powerful computers.Anyway that's not the point, I don't particularly like 3D, or better, it needs to be done VERY WELL for me to be attractive. Most of those games use default lighting and the result are like plastic dolls
But it seems it's fine for a lot of people since otherwise they wouldn't sell so much.Personally I would like to do a 3D because I can do things that with 2D I cannot do - it's more like being a director, you can pick the view you want, have small animations, etc.
Also I wouldn't do those plotless porn games obviously. I would keep doing my usual games but with 3D art.
Being super nitpicky about my work and in particular, the art of my games (even the harsh reviewers had to admit that the art of my games was always at least decent), I wouldn't settle for anything less cute than, for example some of the Until Dawn girls (very cute):
I would never abandon 2D obviously, and perhaps I would even try to see if I can get a anime look in 3D. It's already possible in games but they have custom modeled characters beside cellshading shaders. And it's very difficult/expensive. So for now I am just brainstorming and maybe I could get a powerful PC to make some tests, but no short term plans. It could be nice to make some cash to finance more 2D games of course
