My team and I are getting pretty far along in the development of our latest game and have been thinking about audio. We decided to host an audio submission contest where we will offer a little cash and some equity stake in the game as prizes. We are also giving away copies of the game to participants. We hope not only to find audio for our game, but to meet some cool sound artists and promote the game a bit through the process.
First of all, is this even a good idea? What are some potential dangers in doing this? Will it even be well received among artists?
Secondly, I wrote up some Terms and Conditions in my best legal-speak to try to protect us and clarify how the contest will be run. Are these sufficient to make sure everyone involved is treated fairly and is legally protected? They are as follows:
All submissions (The Submission) must be licensed under a Creative Commons Attribution 3.0 Unported License (CC-BY-3.0)
By applying a CC-BY-3.0 license, you (The Submitter) expressly give Detour Games (and all members wherein) permission to copy, distribute, transmit, modify, adapt, and make commercial use of The Submission.
The Submitter must own all rights to The Submission and be within their rights to license it as specified and submit it.
The Submitter claims responsibility for the legality of The Submission. If The Submission is found to infringe on the rights of a person or entity other than those of The Submitter, Detour Games will not be held liable as all responsibility and liability for the legality of The Submission is that of The Submitter's.
No more than two free copies of The Game per submitter.
All flat cash prizes will only be disbursed pending the success of our first $5,000 Kickstarter campaign. These prizes will be disbursed 30 days after Detour Games receives the Kickstarter funds.
All equity prizes (percentage of profits) are defined as the given percent of total profits after costs for a period of one year (12 months) after the release of RAW. These prizes will be disbursed semi-annually.
All prize money will be disbursed through either an electronic fund transfer through a service such as PayPal or by a mailed money order. It is The Submitter's responsibility to cooperate with Detour Games in the disbursement of the funds.
Detour Games reserves the right to change these Terms and Conditions at any time without notice.
By participating in the contest, The Submitter agrees to and accepts all terms and conditions listed.
What else could I do (legally) to protect everyone involved?
