As a free software activist, I've paid money to buy games that have had their source code released as free software. So while I am part of a tiny minority, I am paying for access to artwork that is designed to work as a game. Yes, I do recognize that people of my demographic represents a negligible amount of revenue to the developer. Some titles that I've paid for include:
• Quake 3 arena
• Morrowind (via the OpenMW engine)
• Delver
• Star Wars Jedi Knight 1 and 2
• Shapez
• Quadrilateral Cowboy
• 0 A.D.
• Hammerfight
