Again a great project: Over at Game-Icons.net a huge collection of free Game Icons awaits RPG fans. The icons can be downloaded in the vector format .svg and in .png format. The graphics are provided under the terms of Creative Commons 3.0 BY license. The collection is still growing week by week.
About the project
All the images are downloadable in a vector format, so you can easily tweak colors, rotation and adjust effects like blur, bevels or shadows.
Another direct benefit is infinite scaling, it means no size limit for the resulting files which can be used for high resolution interfaces, logos, stencils etc...
