rogueNoodle, it's true that our relationship is a partnership and with a 50/50 of any sales i don't need to pay extra. But, in the other hand, hard worked art has it's cost in time and effort and no one can, for sure, know if a game it's going to sale enough or even get released.
So, to cover that possibility, i preferred to paid for the work as is being done.
I talked with my partner-artist and she, since is her first work, is happy to whatever decision i make (contract beforehand).
Thehen, nice insight about your experience. I will take your numbers as a reference.
For now, we are two. Any new member would require a revision to our divisions and payments. For all this my friend/partner agree.
I wan't to cover failure of sells with payment-for-work. The shares for sales is more a matter of my personal decision than a condition from her.
I will take Thehen example as a reference and all your thoughts about not go with big payments if i will share 50/50 in the end. Maybe a cut in the Percentage will work.
Thanks everyone! And any more insights are always welcome!
