Open-source game development assets
Not sure how useful this is, seems like it would be pretty limiting without spending a significant amount of time customizing assets.<p>If your in the market for low-end art, there are offshore studios that produce decent stuff incredibly cheaply. $15-$25 hr range.   Mid to high end stuff is more difficult and expensive to procure for indies since most really good video game artists have full time jobs at the larger studios and not much spare attention for freelance projects.<p>Ideally as an indie you want to partner with a really good well rounded artist who devotes their full time attention to the project, when that happens you get unstoppable teams like 2d boy and team meat.
