To be honest I’d say just charge the $5.
- Epic has to pay for bandwidth as well.
- $5 = free.
- Even if it’s just ~$3 to you, it’s more money that can go towards developing good content and not starving while doing it.
Personally I’m not in a position where I can go donating cash towards cool things, but I really don’t want to get them for free either and I’m probably not the only one.
Perhaps on your website you could offer them for free, and they could be $5 (or more) on the marketplace. This would help to cover your bandwidth/expenses as well.
Or people who donated get the content free, while those of us who did not may also have to pay on your site/the marketplace.
