Congratulations to the winners. Tech jam isn't exactly what I'd like to see, but as long as it's just fun for christmas, okay.
The right thing is that monetization should come from things other than jams:
- Creating clothes for avatars
- Exporting games to Steam (this is where the game author takes responsibility)
- Well own solutions with server code and dedicated servers on linux ?
And then the jams will become more for the fan, and you grow, you realize that you made mistakes when making jams.
