Yeah, my shareware did real well - 800 hours in development, $500 in income across the past 30 years. Oh, and it cost me $400 for the compiler tools back then - so my net profit is rolling in at $0.12 per hour invested. Warning: $440 of that $500 came from an extreme niche product you're unlikely to find such a lucrative vein anymore. My game only netted $60 in return for 400 hours of development, but you could say I got the compiler "for free" off that niche product's income.

I've tried that before, but barely anyone donates. People expect the world for free.
