F2p game profiting?

Why am I asking a dumb question?
Here me out, I’m working on a project alone using Paragon assets. I have no talent in making cosmetics(skins) and I want to avoid any type of micro-transaction. That’s where my problem begins. Is there any other way to make profit for a F2P game on Windows/Mac?

One thing I’m surprised about is that I haven’t seen a computer game(desktops) have any ads in them. Mobile games have it all the time. Is that even an option?

You can always ask for donations and contributions, like many do in itch.io.

It’s generally very difficult to actually make money out of free to play games unless you have a significant amount of money to invest into them in the first place.
