I agree with Oni here. Making a game server is one of your better options. I know of a real-life example from a friend who makes about $1000 every month in donations on his Ark server. He offers in-game benefits like resource drops and boosts for real money. The more you donate, the easier time you have on the server. If you have a big enough server, or enough server instances running, and enough people donating, you can get a nice chunk of spending money. He also gets his wife to post selfies on the discord and plays with the players on the server, and they simp out and donate tons just to play with her. It's kind of genius honestly, and hilarious that people will actually spend money on this stuff.

If there's a game you like, this is definitely a good idea. I don't think I'd recommend doing it just for the money, though.
