Oliver Queen (New Earth)

I've read Gail Simone's Birds of Prey, Mike Grell's Green Arrow, Geoff Johns' JSA, Kevin Smith's Green Arrow, Judd Winnick's Green Arrow. And Specifically Dinah Laurel Lance.

Preferably older stories (New Earth)

My ideas:

Black Lightning game in the style of Infamous

John Constantine

Green Lantern game that would be a bit more exploring of the universe

Green Arrow

Peacemaker
