As you know I wouldn't suggest something without truly supporting it.
This is a Naruto site I'm highly active on and would encourage others to join.
The site takes place 300 years after the story of Naruto (in other words yes to guns) and has a highly active community. The current plot is that Bijuu's have been reborn and are attacking each village, The Akatsuki have been reborn thanks to a mysterious shinobi named 'D' (yours truly) and all in all the world is in chaos and we are in need of heroes so if you feel like it...
