I kinda speed typed my last posts, I should have taken a little longer over them. In particular I should have made it clear that I was not responding to the OP, but to the conversation that followed it.
Basically what I'm saying is if you release a free game which doesn't offer the chance to pay for the game's download, but you accept donations to your game development in general, I'd be very surprised if anyone would have a problem with that, and even if they did, that they would be able to take action against you, regardless of where and when you solicit those donations. When I said now or in the future, I was basically thinking of a scenario like this, for example:
2015 - a developer releases 'Free Game', a free game using a track I have permitted to be used in non-commercial projects.
2015 / 2017 / whenever - said developer starts accepting donations for their game development. Someone donates to them. Let's even go as far as the player sending a note that reads "I just played 'Free Game' and really enjoyed it, here's some dollars to help you continue making great games."
Now, the person received a donation purely on the strength of "Free Game", so in theory I could argue they've profited from a game that used my track, which is only allowed for non-commercial projects, and therefore broken my terms of service. But as it was a donation to the developer, and not specifically a payment for "Free Game", that seems completely unfair to the developer, and I find it hard to believe I could take action against them.
Surely there is a clear distinction between:
1) Allowing someone to pay for the download of a game that uses non-commercial resources, at which point you are offering the customer the possibility to give you money specifically to play that particular game - in my opinion, this is clearly a TOS breach.
2) Giving a game that uses non-commercial resources away for free, but accepting donations as a developer. The game is free, and therefore surely any donations cannot legally be considered as payment for the game. I can't imagine a resource creator objecting to this, and even if they did, I can't imagine it being possible for them to take action against the developer.
Does that make more sense? I'm a little feverish at the moment, it's entirely possible I'm talking utter rubbish, and I'm perfectly happy to be put in my place.
