Hardcore Gaming Twists

Two new rules the High Council of Nerds I game with have been discussing (to spice things up) is the usage of Hero Ponts. (See Monte Cook's Arcana Unearthed. I think they rock) and flexible AC. This rule works by instead of always having a base AC of 10, you role a D20. This -really- puts a twist on things, but can make combat a stomach churning and nervous affair. Still, some neat stuff can come out of it if you don't mind playing a bit more hardcore.
