Hmmmm, this could become a game of picking and choosing, but here's how things stack up (non-Free) Starfighter - Music, sound effects, graphics Metal Blob Solid - Music and sound effects Blob And Conquer - Music, sound effects and likely some of the textures Virus Killer - Music and sound effects Legend of Edgar - Music and sound effects When I was originally approached about packaging the games for Linux distributions, I pointed out that many of the resources were non-Free, but I was told that this didn't matter, since the resources could just be packaged separately. I guess that wasn't really how it worked out. Replacing the resources is certainly an option, but could be very time consuming. However, if people are willing to give it a go, then there is no harm.
