So apparently Unity is going to charge for installations after passing both a minimum revenue threshold from the last 12 months and a minimum lifetime install count. More details in the links, but if this is true, they just killed their own engine. Noone is going to take this willingly, especially free to play games that make no money, or already finished games that cannot just change to another engine. Thoughts?
