Talking about statistics is not pointless, it’s quite interesting sometimes even.
Games like Balatro or Stardew Valley are absolute unicorns. Most smaller teams and solo devs that have a constant stream of some revenue through Steam need to work on the side to earn a living.
That’s Sturgeon’s law (originally 90%). If you want to condense Pareto, it’s “80% of value is created in 20% of the time”.
