Ok, so "all purpose" dotations would be banned. And trademark owners can be really unhappy.
How about specyfic purpose? like
John Smith (proffesional voice actor) blablabla will give his voice for 1000$, we gather money for this, and we have already 422/1000.
Owners/Modders of Blue Planet has no "profit" in this. See billing
Or, go around it (dotations for server webside maintenance) and noone asks where finally money goes?
Or Just Ask trademark owners for premisson or "paid help" with finnishing project.
Or just ignore me, i'm new, ideas isn't new. Things goes like it goes and it's fine. Just time.
In the other hand,
I'm pretty sure, where money goes, expectations raises. "I paid for this, blahblahas, and id dint..! *complaint* *complaint* *complaint*.
For Me,
i've already played a really great part of game and i know someone did it for me for "free" . I feel i took some debt, so dotations would be the simplest way for "repay" even if unfair with $/hour.
(Im sorry for my english, what you see above it's just years of playing "online", not proffesional lessons, i hope it's understandable)
