So I gave 4E a second chance with Essentials and played some D&D Encounters just to get some games under my belt. I have to admit I like it. Then I tried out 4E Gamma World, and after some major tweaking, it plays more like the original (one origin, no rotating mutations) but with all the bells and whistles.
I then finally tweaked the 4E Gamma World into a modern Super Heros game nicknamed "Champions and Vigilantes". Has anyone else tweaked the 4E system into a Super Heroes game? We've played a few sessions and are having a blast. three of the players are kids, two girls aged 8 & 10 and one boy, 13.
