In Gamasutra's latest feature you'll find comparisons of available crowdfunding options for game development, including Kickstarter, 8-Bit Funding, and more -- complete with quotes, explanations, and a handy chart.
The best-known service is Kickstarter, which is not specific to any particular type of project, and funds games. However, R. Hunter Gough, writer of the feature and experienced indie developer, argues that "Kickstarter is the most well-known crowdfunding service, it may not be the best fit for every video game project, so we're taking a look at five different crowdfunding services for video game projects to help you decide what will work best for your needs."
He continues, "The biggest core difference that separates these crowdfunding services is the funding model. Kickstarter and ulule both use an "all or nothing" funding model, meaning that no money exchanges hands until a project's deadline is reached, and only if the project has also reached or exceeded its funding goal.
"IndieGoGo and 8-bit Funding both use a 'keep it all' model where funding is paid immediately to the project, regardless of whether or not the project reaches its funding goal by the deadline."
