I wouldn't be against it.
Supers is such a weighted term. It can cover the classic 4 color comicbook wackiness, more serious tv drama empowered normals, urban fantasy, psionic mystery, and just about any lighter transhuman plot. I've run so many games based on this concept. I have a loose circle based on the topic. If you are intested in my world building, concept testing, and eventual game sessions based on supers...let me know to add you.
What a coincidence! I am just about to start a Champions campaign and could use anything I can plagerize... er... learn from! :)
I started into RPGs with Supers. TSR Marvel Super Heroes Yellow Box to be exact. Feel free to add me :D
