My group and I saw Champions and then blinked at the 86D6 on one sheet and gave it a pass.
What was that? Dark Phoenix eating a sun?;)
Seriously 12d6 is normally as high as you go in early campaigns, 16 in late and *maybe* 20d6 for epic level campaigns. But the kicker is d6 is pretty much all you need, no other polygons, so you can always scavenge from games of monopoly etc .
Champions PnP is based on the HERO system which is, hands down, the BEST most flexible system I've ever seen for simulating, well, ANYTHING.
Like any new system you have to look at it and wrap your head around the way it works, but it's REALLY elegant and fantastically flexible. HERO system can do ANYTHING.
At least in New World of Darkness becoming one type of Supernatural precludes you from becoming others. It should be impossible to have a Vampire Werewolf for instance. Old World of Darkness I can't speak on, beyond I've heard that it's really bad if you embrace another Supernatural but no one actually told me what happens!
I'd try HERO but I don't know enough people in real life that would be interested in such a detailed and involved system. Most of us enjoy things like Traveller or Storyteller because they're simple and easy to adapt.
