How to negotiate with the artist and what licenses do the images have?

Question

Freelance

Good day to all, 2 points are interesting,
1) Is it possible to agree with the artist, they say, draw and 25% of your sales? Or just pay now? How does this system work in general? How does an artist know if I'm lying?
2) If I want to take images from the Internet into my game, there are a ton of free and pseudo-free licenses, can you explain this question in 2 words and with what license to look for sprites, etc.? or at least give a link where everything is short and simple, I'm confused in them :\
Thank you in advance
In the near future I plan to try to make a platformer, now I'm studying this issue a little

Answer 1

They want to order everything for a percentage, every second one is looking for a student who will do everything for "free", of course, there will be no percentage.
A normal artist will not work for even a word, and most likely, you will have to be ready to give him an advance payment for the project.
And also, if you are confident in your idea, I would not advise everyone to give out interest, because it is much cheaper to pay.

Answer 2

I answer 1 question.
Any agreement can be made. Modicum on greyhound puppies to change. The main thing is that a contract must be concluded. Finding out that you are not lying is easy - you give access to statistics.
But only young students agree to work "for a percentage of non-existent garbage."

https://illustrators.ru/ - they draw here, you can find it inexpensively.
https://opengameart.org/ - drawn here and given away for free

Answer 4

Is it possible to agree with the artist, they say draw and 25% of your sales? Or just pay now?
Unlikely. Find an accomplice faster if the project is under an open license (MIT, GPL, etc.).
For beginners, this benefit is greater than the mythical interest.

Answer 5

For question 2 - from non-commercial public domain (Public domain = PD = CC0) and "indicate the author" (Creative Commons Attribution = CC-BY) are suitable. No other CC licenses for a commercial game are good!
If the game is open, think about what license it will be released under and whether the requirements are compatible with this license. For example, PD = CC0, CC-BY, CC-BY-SA are compatible with the GPL.
Of course, it is possible that some parts of the game are under one license, while others are under another. For example, the engine is GPL, and the images are under a stricter or softer license. So, Doom (1993) has a GPL engine and everything else is commercial.
Each semi-commercial license has to be considered separately.
If there are several licenses (for example, CC-BY + GPL2 + GPL3) - if there is at least one among them that suits you, that's fine!

Answer 6

1) Is it possible to agree with the artist, they say draw and 25% of your sales? Or just pay now? How does this system work in general? How does an artist know if I'm lying?

It's a matter of trust.
If you agree, you can.

Answer 7

The percentage is very interesting.
Finding for a percentage when both parties are satisfied is such a rarity.
At first, they don't trust you or don't believe in the project, and for a percentage, people go to work who are not able to do something good.
Then people want to work with you for a percentage, but with many it is not interesting. It's easier to pay them a fix and have no obligations.
And I can say one more thing:
I have never successfully worked with an artist for a percentage. Although they worked once. He was a reliable person, but then they parted ways peacefully with the payment of the golden parachute, of course.
Item 2. This is for lawyers. There are many licenses, there are many nuances. If you work with someone, then have a license agreement with him. There is also an author's order.
