Yeah, you need to add more languages and frameworks, and not just the things that are out and popular now. I'd want to include projects from awhile back, personally, and that includes projects made from Flash. I know its unfashionable now (and I no longer use it), but it's how a lot of devs got started.

If you want game developers to find this useful, you might want to consider adding:

C++, C, Unity, Unreal SDK, Cocos2D, Lua, Flash, Havok, Direct X, OpenGL, VR. Maybe show a list of consoles to show specific console dev experience.
